Hello everyone, I am Taotie I think when it comes to small-sized keyboards, many players will think of the popular 68% configuration. Because it retains 60% of its compact shape and also adds direction keys and some function keys, it is relatively balanced in size and function. However, for players who need to frequently tap numbers, 68% of the arrays lacking a small keyboard are still difficult to perform more tedious number tapping tasks. Indeed, in the choice of functionality and form factor, such pain points do leave a certain market space. Of course, where there is a market, there are opportunities. The upstart GM780 displayed this time is such a mechanical keyboard with a special arrangement. This upstart GM780 adopts a very unique 75% key arrangement. While cutting off the F area, it retains the arrow keys and the number area, which perfectly solves the problem of small size and no number input. At the same time, this keyboard also has Bluetooth, 2.4g Wireless and wired three-mode connection, real Gasket structure, co-branded Dailuo switch with Kaihua, black transparent PC shell, original height PBT two-color keycaps, hot-swappable and other rich functions. OK, the introduction is almost done, let's take a look at the actual performance of this upstart GM780 three-mode mechanical keyboard. The packaging of this upstart GM780 three-mode mechanical keyboard is very dreamy, and the combination of pink and purple also complements the keyboard theme. After opening the package, you can see the keyboard body, and you can see that it also comes with a transparent dust cover. For me who lives in a northern city, I must like it. The accessories that come with this time are quite rich, including a two-in-one tool for pulling out shafts and keys, personalized supplementary keycaps, power cords, four replaceable shafts, and manuals. The first impression of this upstart GM780 is that it does not look like a mass-produced keyboard at all. Whether it is color matching, shape design, or material materials, the visual effect is unique and different, completely out of the mass-produced company. model impression. The theme in my hand is called "Fog Mountain". Although I can't guess what it has to do with the fog, the overall color matching is still unified and harmonious. The light purple letter area and the light gray functional area have a natural transition. Coupled with the color bar on the forehead, I inadvertently think of the taste of retro "vapor wave". Speaking of retro, the large raised forehead on the front also has that kind of nostalgic feeling. As I said at the beginning, this upstart GM780 adopts a very niche 75% arrangement, that is, the F area is cut off, and the direction keys and number areas are reserved, and each partition is partitioned to avoid overcrowding and accidental touches. The keyboard on the shell is made of black PC material, and the edge is processed with multi-layer wiring, so that the overall look will not be too monotonous. After all, it is not a hull structure, so the edges are a bit thick, and it is best to add a palm rest when knocking to avoid hanging in the air. On the left side of the end are the power switch key, connection mode selection key and Type-c interface. Turn it over, you can see that the bottom of the upstart GM780 has a whole piece of rubber pad, so there is no such effect of seeing through the PCB directly. Below the bottom metal nameplate is the storage compartment for the 2.4g wireless receiver. The foot support adopts a three-stage structure, which is convenient for players to find a suitable tapping angle. In terms of the shaft body, the upstart GM780 I experienced this time uses the Dailuo shaft co-branded with Kaihua, and the feel type is advanced paragraph. I tried it with my hands, and the smoothness and stability when knocking are still quite poor, but some shafts have a little "sand, sand" noise, which may be improved after the shaft is lubricated. The big key position is still the traditional positioning board satellite shaft, which is very firm when shaking, and grease is added inside. This time the upstart GM780 adopts a real Gasket structure, and its internal leaf spring structure can be seen through the transparent shell on the side. https://woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo. Through a video to feel how the percussion feel of this product is. In addition, this upstart GM780 has also added a hot-swappable base, which is more playable and easier to maintain later. In terms of keycaps, this time it uses the original height of the PBT two-color keycaps, which is ergonomic. Although I don't know which OEM it is, but after looking at it, the overall quality is quite good, the characters are consistent in thickness, the surface feels smooth, and the color matching is also in line with the theme. In addition, the personalized keycap with five-sided sublimation is also outstanding, with bright colors, high saturation, rich images and even coloring. After all, it is a transparent shell, so it can show a crystal clear feeling in terms of lighting effects. However, since the keycap is still made of opaque PBT material, the overall light effect is actually dominated by the ambient light, which can be used to enhance the atmosphere. Finally, I tried the wireless connection, and the connection stability is good. The 2.4g has a slight delay in use, but it has no effect on the codeword. Through these few days of use, I found that the performance of this upstart GM780 three-mode mechanical keyboard is quite excellent. First of all, this keyboard has a good experience in appearance. The large forehead with a retro feel, the black PC shell, the color matching of light gray and lavender, and the more balanced 75% configuration make this upstart GM780 three-mode mechanical The keyboard is eye-catching, coupled with the co-branded Kaihua Dailuo shaft body, RGB lighting effect, hot-swappable base, PBT two-color keycaps, three-mode connection, etc., it is almost impossible to find a big keyboard in the user experience. blemishes. So if you have the pursuit of a keyboard's appearance, feel, and configuration, then this upstart GM780 three-mode mechanical keyboard is really worth a try. Well, the above is the whole content of this article, thank you for reading!

As a serious music lover who turns on the music player at startup, the multimedia function has always been the main consideration when I buy a keyboard and mouse. First, let me introduce the keyboard I am using: The keyboard I used before was Logitech G710+. This keyboard uses cherry green switches, which feels good in the hand and has a very special sound. It is very exciting to type. Four-level adjustable backlight design, the commonly used game button MASD can individually adjust the light for easy and quick identification. 6 programmable shortcut keys can provide up to 18 groups of macro memory, which is powerful. It can be used to store game shortcut key combinations and remember passwords, which is very easy to use. There are also four multimedia playback buttons, playback pause/stop/forward/backward, mute button and volume adjustment activity adjustment buttons, which make playing music faster and adjusting volume more casual. A detachable bowl holder is provided for better handling. Although the G710+ keyboard is very wrong to use, the keyboard cable affects the cleanliness of the desktop, and the obsessive-compulsive disorder cannot bear it! So I started with Logitech's Logitech MK710 keyboard. The advantages of choosing this keyboard are: 1. There must be a multimedia button, which can quickly switch songs and adjust the volume conveniently 2. Wireless, which can ensure that there is no cable on the desktop, making it more tidy 3. With wrist rest, it feels more comfortable. After using it for a period of time, I found that this keyboard has several shortcomings: The hand feel is relatively poor, and it does not have the smooth feeling of a mechanical keyboard. The raised part on the front affects the appearance, and the more you look at it, the uglier it is. How did you choose such an ugly thing in the first place? People are really strange animals, so you embarked on the road of searching for multimedia keyboards. This time I chose with 3 demands: 1. Mechanical keyboard, can guarantee the feel 2. There are multimedia control buttons, this is a must 3. Smaller, the previous two keyboards were too big There are a lot of digital experts on the site, and I often see value friends posting various keyboards, and I have a better understanding of keyboards. Now there are more and more mechanical keyboard switches to choose from, no less than 20 types, and there are as many brands as crossing the river. Among the many keyboards, the keyboard of the Keychron brand caught my attention. Several bigwigs showed that there is an adjustment knob on the Keychron keyboard, which looks very cool, and I feel that this brand should have a keyboard that meets my needs. The Keychron brand doesn’t seem to be very well-known in China. After Baidu, the keyboards of this brand are quite popular abroad. One of the keyboards was selected as the third most popular keyboard by the New York Times this year! It's not easy! I have always used Logitech keyboards before, so I just tried another brand. After looking around, I found that the Keychron K1SE keyboard is quite good. This keyboard adopts a streamlined 87-key layout, which is the same as the commonly used laptop keys. While reducing the size and increasing the desktop space, it maintains daily use habits. Using Jiadalong short switch, it not only has the comfortable pressing feeling of the mechanical switch, but also has the thin and light design of the notebook, which is unique. Built-in charging, support wired and wireless dual-mode, can switch between multiple devices, very convenient. It also supports Windows/Mac OS dual system adaptation, and the function is quite powerful. The most important thing is: not only does it support multimedia control, but it also has a black + gray design that I like, isn't this just tailor-made for me? Ha ha ha ha After 3 days of long waiting, SF Express finally delivered the keyboard. It is packed tightly with shock-absorbing airbags, praise! On the front of the black packaging box is the outline drawing of the keyboard, and above the keyboard is information such as the trademark and brand model, which is simple yet stylish. The bottom of the box is the function introduction and the physical picture of the keyboard. The packaging box is designed with a sky and earth cover, which looks tall. The following is a welcome unboxing link: When you open the top cover, the first thing you see is a black sponge. Through the sponge, you can vaguely see the red card below, which is very exciting. The box is divided into two partitions, and the top is accessories such as USB cables, shaft pullers, key pullers, and replacement keycaps. The red card is the operation prompt for installing the shaft body, the white card is the keyboard quick start guide, and there is also a keyboard manual in Chinese and English. Further down is the main body of the keyboard, which is tightly wrapped in a layer of plastic bag. Lift up your hijab and show me your beauty! Remove the plastic bag and there is a hard plastic keyboard protective case, which is well protected. It can also be used as a dust cover when the keyboard is not used for a long time. Finally see the real face of the keyboard! The orange ESC key in the upper left corner is the finishing touch, it looks very smart and very aggressive! Provides six replacement keycaps, Windows/Mac OS dual system adaptation. If you don't like the flamboyant ESC key, you can also change it to a gray one, depending on your personal preference! I also changed the light adjustment button to orange, is it like two horns? appearance and design This keyboard is really simple, there is no extra design on the keyboard, not even the brand LOGO, it is really too low-key. Ultra-thin body Ultra-thin shaft body design, the size is only 346 x 118.5 x 24.5. The newly designed Jiadalong low-profile switch is 40% thinner than the traditional switch body. It is designed with light and thin aluminum alloy. The thickest part of the keyboard is only 22 mm, which is very slim. The shell adopts an overall metal design, and the four corners are rounded, with fine workmanship and no burrs. Because it is made of aluminum alloy, it weighs 550 grams. The keyboard is not big but has a lot of weight, and it is easy to hold it in your hand. Compared with the traditional Jiadalong green shaft, it is much shorter The contact position of the mechanical axis is also different Similar to the ultra-thin keycap of a notebook, this keycap worth 188 oceans is temporarily unavailable overlook Foresight rearview side The layout of the keyboard is slightly different from the conventional keyboard. The keyboard indicator is designed to be next to the ESC in the upper left corner of the keyboard. There is a bluetooth indicator and a caps indicator, both of which are blue LED lights. The F1-F12 area integrates the function keys commonly used in notebooks, such as brightness adjustment, and my favorite multimedia control keys. Because there is no small number pad area, the number area switch and screen printing keys of the conventional keyboard are designed as lights. Mode adjustment and other buttons. It can be seen from the keys that this keyboard is more MacOS-oriented, and Apple laptop users can use more functions. So this keyboard is also installed with MacOS keyboard keycaps. Users can replace it according to their needs. The bottom surface is made of plastic material, and the left and right sides are adjustable foot pads, providing 2 levels of adjustment. Apart from a nameplate tag and five racetrack-style rubber guards in the middle, it looks very comfortable. The keyboard adopts a 2-stage foot support design, and three different angles are available for selection, which can be selected according to individual needs. There are two function selection keys behind the ESC key on the keyboard, and the left one selects the Bluetooth mode switch and the wired mode. Choose Win/Android Mac/iOS on the right, and the factory default is on wired and Mac mode. In the middle is the TYPE-C cable interface. Experience It is recommended to charge it for the first time. The keyboard has a built-in 2000 mAh battery. It takes 3 hours to fully charge with 5V1A, and the battery life can reach 35 hours when the light is turned on. In the wired mode, connect the keyboard to the USB port of the computer with a cable and use it, so I won’t introduce it here. The keycap has a skin-like varnish with a fine frosted touch, similar to the appearance of a chocolate keyboard, and feels very good. The light transmission effect of the two-color injection molding process is just right, the light transmission line is very soft, the edges of the characters are very sharp, and the workmanship is very delicate. This keyboard shaft body supports hot swapping. Remove the keycap and use the shaft puller to take out the mechanical shaft, and then press to install it to complete the shaft replacement. bluetooth mode Turn the toggle switch on the back to Bluetooth, press Fn + X + L on the keyboard, turn on the Bluetooth function of the system, add Bluetooth or other devices, click Bluetooth (mouse, keyboard, stylus, audio equipment and other types of Bluetooth devices) , you can search for Keychron K1SE, and click it to pair and use it successfully. The keyboard supports Bluetooth 5.1 mode, and the response speed of the keyboard in Bluetooth mode is also very fast. I tried to play Diablo 3 in Bluetooth mode, and it feels similar to the wired mode. The feel of the keyboard is slightly different from that of the Cherry Green switch, and the paragraph feel is a little weaker. You can’t tell the difference without comparison, because the keycap is smaller, and the percussion force is also less laborious, and the sound is crisper than the Cherry Green switch. The sound of K710+ is relatively deep, while the sound of K1SE is relatively crisp, which is different from the original K710+ with a new feeling of green switches, and the feel is quite good. After using it for a few days, I feel inseparable. This keyboard supports switching between three Bluetooth devices, which can be switched through the key combination fn+1/fn+2/fn+3. In Bluetooth mode, if there is no operation on the keyboard for ten minutes, it will automatically enter sleep mode, and the backlight will turn off. Tap any key to wake up the keyboard. When the power is lower than 15%, the power indicator light will flash red. You can also press and hold fn+S+O for four seconds to turn off the automatic sleep mode, and press and hold again to turn on the automatic sleep mode again. Function key switch Press fn+X+L at the same time for four seconds to switch between the multimedia keys and the F1-F12 function keys. The multimedia function keys of this keyboard are relatively centered and can be operated with the left hand without putting down the mouse to select. In this way, as long as the music software is running in the background, you can easily cut songs and adjust the volume, which is very convenient. Press F3 to quickly switch between multiple desktops and improve work efficiency. A good companion for laptop users, you can enjoy the comfort of a mechanical keyboard even on business trips. The size of this keyboard is very miniature, not much longer than a piece of A4 paper. The included keyboard protective case can protect the keyboard from accidental touch. The keyboard is light and portable, and can be easily put into a computer bag. It is also very convenient to carry on business trips. Finally, let's talk about the lighting mode: This keyboard supports 15 lighting effect options. Each time you press the lighting effect switch key, you can switch to a mode, cycle switching, and you can also turn off the lighting effect to save power. The standby time can be as long as two weeks when the light is turned off, and the battery life not bad! I like the mode of pressing which button turns on which light, and no button is a holographic light. Also quite energy efficient. There is also an RGB lantern version to choose from, which is a good choice for friends who like to play with lighting effects. Summarize: Ultimate simplicity! Taking into account both appearance and function, small and exquisite beauty! After a few days of use, this small keyboard is full of surprises for me! The workmanship is superior, the design is very careful, and the appearance is also very good. This switch body is slightly smaller than the conventional blue switch, and the sound is also slightly lighter, which feels better to use! The design of the multimedia buttons is very thoughtful, and the position is in the center. It is very convenient to switch songs while typing. Unlike many 108-key keyboards, the position of the multimedia control keys is relatively to the right, and it needs to be specially set aside for operation, so it is better to use the mouse to control. For notebook users, this keyboard can provide a better sense of control and effectively improve efficiency. Small and portable, you can enjoy the joy of a mechanical keyboard even on business trips! If you are looking for a mechanical keyboard with good looks, many functions and easy to carry, Keychron K1SEG2 is your best choice!

As a keyboard manufacturer, Dujia has launched a lot of good products, whether it is a wired keyboard or a wireless keyboard, with light or without light, 100% configuration or 80% or 60% are available, and the appearance is online, and the feel is also online. I have also used K320W, RGB-NS, Fusion, K330W, etc. In fact, the changes are very obvious, both the appearance and the functionality are constantly enhanced, and like the latest Durga K610W/K620W, I think it is currently the most versatile mechanical keyboard in Durga. The appearance of Durga K610W/K620W is available in two colors, matt-echo and matte-island, which are fog blue and dark green respectively. I chose fog blue because I prefer blue. The design of the packaging also follows the color change, but it is generally similar to the previous one. The difference between K610W and K620W lies in the key positions. This setting is similar to that of K310W/K320W. 610W has 104 keys, and 620W has 87 keys. I don't use many small keyboards, and 104 keys are too big for me, so I chose K620W-87 keys. The outer packaging is also blue and white, with the front view of K620W on it, the wireless mechanical keyboard K620W in the upper left corner, the DORGOD logo in the upper right corner, HOT SWAPABLE in the lower left corner. Die three signs. There are also some main information on the side, such as the introduction of functions, size parameters, shaft body, etc. The size is 359mm long, 142mm wide, and 37.5mm high. The weight is 1042g, which weighs two catties. It can be seen how much material is used. The Jiadalong black crystal red switch used in the switch body is an old friend, and its performance has been very stable, and it is also very suitable for office, game and other situations. In the accessories part, there are classic set manuals, shaft pullers, key pullers, straps, Type-C to USB data cables, but there is a new accessory, and there are 3 extra keycaps. If you look carefully, there are two CMD keycaps And an OPT keycap, everyone who has used Apple knows that these three buttons are the buttons in macOS. So K620W has made an improvement that makes me very comfortable. It supports the Mac system, and can automatically identify the system, automatically match the key positions, and then replace the corresponding keycaps and wait for it to be used as a Mac keyboard. It's really fragrant. The appearance of K620W is very good-looking, and the color matching is also good. The blue ESC, space and carriage return are used as embellishments, the functional area is mainly gray, and the input area is mainly white. The middle frame is mainly black. At first glance, only the white front surface can be seen floating on the desktop, reducing the visual volume. Supporting three modes is also one of the reasons for its versatility. It can connect two sets of Bluetooth devices, and can also reduce delays through 2.4G wireless connections. This is more suitable for gamers, and it can also be used with wired connections. It can meet the needs of various scenarios, like I usually do. It is more suitable to use 2.4G wireless connection when it is used for codewords and games, and you want to make your desktop wireless. If it is a simple office and wants to go wireless, then Bluetooth is very suitable. Regarding the battery life, the official also gave relevant data. It takes 3 hours to fully charge under the power of 5V2A. And if you use it in Bluetooth mode, because of the no-light design, the battery life can be 360 ​​days of continuous work for 8 hours a day. If it is 2.4G wireless, it can achieve 200 days of battery life, which is satisfactory for daily use. . K620W is still a full-key non-conflict design, which does not limit the number of key combinations. For example, office or games often need to press various key combinations, and PS will press several keys at the same time, so full-key non-conflict is still very necessary. The keycaps are all PBT two-color keycaps with the height of the original factory. Needless to say, the advantages of PBT material are that the front of the keycaps made of two-color closed molding technology makes the fonts not easy to wear. For example, a blue keycap is a combination of blue and white, a white keycap is a combination of white and gray, and a gray keycap is a combination of gray and dark gray, and there is also a little color deviation. The K620W series is a full-key hot-swappable PCB design, all the switches can be replaced at any time, DIY belongs to your own keyboard experience. The original axis body uses the crystal axis customized by Dujia and Jiadalong, which belongs to Jiadalong CAP axis, but with the optimization of Dujia, the crystal axis is very comfortable to use. The black semi-transparent shaft body is also very good-looking. The pin part is connected by two pins. It can be pulled out with a shaft puller. The installation is also very simple. Large items such as carriage return, space, and shift are all designed with satellite switches. I feel that they are similar to single keys when pressed, so Dujia has also worked hard in this regard to restore the feel of the key switches. There are 4 indicator lights on the direction keys, and the indicator lights are also set with a separate gray twill background. From left to right are upper and lower case/Bluetooth 1, lock key/Bluetooth 2, configuration file indicator/2.4G wireless, battery indicator, This configuration is very nice. The design on the back is also very aesthetic, the bottom is narrowed, supported by blocks, and the height is different so that the keyboard itself has a certain inclination. The logo of DURGOD in the middle is surrounded by the upper and lower blocks to form the effect of a nameplate. The labels have also been moved to the upper middle. There are small non-slip pads at the corners. The feet support two levels of height adjustment, and the 2.4G wireless receiver is also cleverly combined at the bottom of the keyboard, with its own independent storage compartment, which is to be praised. Durga K620W weighs 1042g, and the internal structure uses a lot of materials. From top to bottom, there are PBT keycaps, shaft bodies, upper covers, metal positioning plates, silicone pads, PCB boards, sound-absorbing cotton, and bottom shells. In order to improve the experience, the structure Adding silicone pads and sound-absorbing cotton can effectively reduce the generation of noise, and can also play a shock-absorbing effect. K620W also supports Dugazeus driver software, which can edit keyboard keys, play macros or edit one or several sets of exclusive configuration files of its own. It also has an onboard storage configuration function, so that the configuration file in wired mode can be used in 2.4G wireless mode. The appearance and configuration of Dujia K620W personally feel that it is one of the most versatile mechanical keyboards of Dujia at present. Except for the lack of light, it basically has everything that one expects to find, and also heard the voice of users, adding the Mac adaptation, and automatic recognition , but the keycap needs to be replaced by itself, which is relatively troublesome. In fact, you can add the corresponding Mac print on the original keycap. Anyway, it is automatically recognized and switched automatically, so for friends who are dual repairing Windows and MacOS Switch seamlessly. Three-mode wireless, supports two Bluetooth devices and one 2.4G wireless device, which is also satisfactory for multi-device users. The black crystal switch body customized by Dujia and Jiadalong has also passed the test of the market. The condition of the large key is comfortable, and it has a good experience whether it is gaming or office work. And thanks to the matte design, the battery life is quite long, and it is a small problem to use the Bluetooth mode for a year. The above is all the content, if you like it, give me a thumbs up!

Two days ago, there were cute comments and private messages asking if the rx980 can be dismantled, this time I will dismantle the rx980, three-mode, 98 keys Although it is a disassembly, I was quite sad when I opened the courier bag and scratched a line on the box. The courier bag is the packaging box of this keyboard. I started with the red axis, and the lollipop I chose was the color combination of blue, pink, and white. It is an accessory with a full complement of keycaps, In terms of color, it can be supplemented with a blue and white keyboard The keycap has a small space, B key, step-style caps, 7-character carriage return, and several game keycaps. Just relying on the keycaps that come with it, it is enough for daily use The color of this keyboard is also very small and fresh, this is the feeling of summer, and it is a bit milky. The whole machine is also 2 catties and 9 taels, which is 3 catties, which is really not light The lower right corner is the logo on the metal nameplate At the bottom of the back is the switch button for windows, mac and three modes. The default is to point to the wired one. This is actually good. If you use the wired one, you can switch to the wired one. It is more mechanical and easy to understand. The C port is relatively wide, with slideways on both sides, and the built-in data cable does not have a card position for this slideway It is also a three-way winding There are two levels of feet, but there is a magnetic usb receiver hidden under the left foot, which is also designed to prevent loss and fall Then there is the metal nameplate Its keycaps are concave and have curved radians. The small keys are low in the front and high in the back. The corners of the keycaps are also treated with obtuse angles. The two-color injection molded PBT feels smooth, and the bright ones can reflect light, like candy. kind of has 2 heights The satellite axis is very tight, and the big keys are very stable when they are tapped left and right, and the typing force is basically unshakable. When typing, there is an obvious knocking sound like knocking on wood, without other noises, and the smoothness is good The trigger stroke is about 1.8mm, the bottoming stroke is 3.8mm, the rebound is fast, the bottoming is relatively stable, suitable for coding The pressure is 43gf, and the key travel is moderate and not deep. In fact, I was also a little entangled in why I didn't choose gold powder at that time. The next thing is to take it apart The shell is buckled, and the back slides to open. When pulling out the shaft, I feel that it is so easy to pull out. Even in a keyboard, when removing the keycap, I just slide it down four or five times. The last time I pulled out Kaihua, some of them almost made a miracle with great effort, but that one was stuck really tight This is TTC's Jinhong pro, with factory run, three-legged There are 2 sponges next to the space There is a mute pad between the PCB board and the positioning board, and the positioning board is also a piece of metal, which is very heavy It supports three-legged and five-legged, and this comes with a three-legged red axis Unplug the pcb board connection line at the back and take it down At the bottom is a very thick silicone pad, the opening is very accurate, the kind that fits perfectly The battery is 3000mAh The battery is directly stuck in this groove, and there is a sponge on it, It was okay when I disassembled it, but when I installed it, I wanted to complain. Of course, there is no need to complain if it is not disassembled. One is that the battery is placed in the slot, although the space is just right, but after disassembly, as long as the board is picked up, the battery will either fall down, or when it is closed, I always worry that I won’t be able to reach the card position, afraid of being pressed , so I ended up adding a tape to it The second is the connection line of the PCB board. A very wide rectangular line slot is reserved. adhesive tape The Bluetooth 5.0 used in this keyboard can also use the usb receiver and cable. The driver downloaded from the official website can be connected in both Bluetooth and 2.4G wireless modes. It is possible to change key positions, macro programming, and set music rhythms. This keycap is not light-transmitting, so the light also goes to the four sides. The intensity of the light is average, and it will not be too eye-catching during the day. The brightness and color can be adjusted, and the playability is good
