The last Duga K620W wireless keyboard with a mute red switch was used by my wife in the company, so I thought about adding a mute wireless keyboard to the desk in the bedroom. I bought a lot of Duga keyboards, and I have a good impression of the Duga brand. The wireless and Bluetooth are also very stable, and the chain has never been dropped. But I am unwilling to buy another K620W of the same model, because I have used it. After Dalong’s silent red switch, I feel that I have discovered a new world, and I want to experience Kaihua, Gaote, and TTC. But just in time, when I paid attention to Kaihua, I found that Kaihua has launched a new Turbo shaft. The shaft core material of the "Turbo" series of shafts is made of high-smooth composite POM material newly developed by Kaihua, which is highly smooth. High performance and low coefficient of friction for a smoother experience. And the first launch of this Turbo switch is Dujia’s new K620W white light version of the three-mode wireless mechanical keyboard. Compared with the K620W, the K620W white light version not only has more lights, but also the switch body has been changed from Jiadalong’s customized crystal switch to Kaihua Turbo. axis. So, I bought another keyboard with exactly the same appearance! That's right, the K620W in front of me is also the "Echo" in blue and white color. I like the appearance, so I also chose the same appearance for the white version of the K620W I bought. Not only the appearance is exactly the same, but the packaging and accessories are also exactly the same, except that the word CORONA is added on the packaging. Duga K620W echo color, pure white panel, pure white letter area, with light blue functional area, with Klein blue as the finishing touch. And because it is a light-transmitting keycap, the characters are made of light gray translucent light-transmitting material, so the contrast in appearance is not high, it looks soft and low-key, elegant and restrained, and you will never tire of it. The keyboard shell of the sandwich structure is essentially an improved hull structure. The shortcut key function is marked on the side of the keycap, so it looks cleaner and tidy from above. I found a small change, the WIN key and the Alt key directly became the dual system logo, and the Option and Command of Mac OS were also marked, so that there is no need to change the keycaps when switching systems! Due to the white light, the keycap is also replaced with a light-transmitting keycap, light gray translucent light-transmitting material + PBT material two-color injection molding. Durga's keycaps have always been very good in workmanship, with no obvious spouts, neat edges, and uniform colors. The hot-swappable Kaihua Turbo silent red switch, the high-transmittance switch cover, and the sheathed cross keycap can effectively prevent dust and foreign objects from entering the switch. The hidden receiver storage compartment is more beautiful and not easy to lose. Two-stage folding foot pad, height adjustment more freely. Compared with K320w Misty Blue, we can see that K620W has a more mature color scheme and more delicate handwriting. I like both colors! In terms of workmanship, both are very good, but the workmanship of K620W is more complicated, so it has a sense of class. On the desk in the bedroom, just right! The main color of white matches perfectly with the pure white table top. The blue embellishment just sets off the red mouse. My wireless earphones are also white, Samsung Level Over Bluetooth noise-cancelling wireless earphones, which have been used for many years, and they are very coordinated when put together. The speaker is relatively low. I originally wanted to buy the white version of the Audioengine A2+ Wireless. It is small and exquisite, and the sound quality is not bad. Unfortunately, my wife does not approve... Dujia K620W white light version, the light is soft, not dazzling, and looks comfortable. There are many modes of light, such as constant light, wave, ripple, superficial water, starlight and so on. Of course, turning on the white light consumes more power. As a wireless keyboard, I usually turn it off. The structure of the Durga K620W is based on an improved hull structure, similar to the Gasket structure, and it also uses a large area of ​​sound-absorbing cotton and cushions, so it is also very quiet. I also have a Gasket structure keyboard on hand, but in fact it is difficult to feel the structural difference from the K620W in use, and the shaft body has a greater impact on the feel. There are four types of Turbo switches newly launched by Kaihua, red switches, silent red switches, silver switches, and brown switches. My model is a silent red switch, and the conduction stroke is a little shorter than that of the red switch, which means that the trigger will be a little faster, but in fact, most people can't feel the difference at all. In terms of feel, compared with the cherry red switch, the Kaihua Turbo switch is obviously smoother, without friction, more stable and less shaking. The end of the silent red switch has a rubber cushion to reduce impact noise. The Q elastic has a little cushion, just like running in running shoes, with less impact and a less crisp mechanical feel, but it is more comfortable for long-term use. And the sound is indeed significantly smaller than the ordinary red shaft. The feel of this kind of Q bomb is a bit close to that of an electrostatic capacitor keyboard, so it is the same as the electrostatic capacitor keyboard. People who like it boast that it is the ultimate fever reduction, while those who don’t feel it feels like wearing a cover, and there is no pleasure. Compared with my K620W K620W’s K620W, the pressure, stroke, and conduction are basically the same. However, the Kaihua Turbo’s silent red switch has more sheaths and structural reasons. I feel that the upper shaft is shaking. smaller. It feels good in the hand. The last K620W was taken by my wife to the company, so I can’t make an AB comparison between the Kaihua Turbo silent red switch and the Jiadalong silent red switch. It’s a pity! In general, the Dujia K620W white light version of the silent red switch meets all my expectations - exquisite, elegant, quiet, smooth, long battery life, and stable connection. This is why I bought the K620W again! Editor's Note: The author of this article @黑夜王子 is what is worth buying as a chief lifer.

I have played a lot of mechanical keyboards, so I can't be said to be a player, but I have seen the world. Most mechanical keyboards are almost the same, giving people the feeling of being too old-fashioned and lifeless. Since the shaft body is a few well-known ones such as Chrery, Kaihua, and Jiadalong, the so-called customization is nothing more than making a fuss about keycaps, shell materials, such as aluminum and other non-plastic materials, keycap design, etc., and we Ordinary friends are actually just experiencing keycaps with different designs. In order to cater to today's younger market, Dujia recently launched a very fashionable and novel Hi Keys dual-mode wireless mechanical keyboard. In terms of layout, Dujia Hi Keys chose a compact 84-key arrangement, cutting off the numeric keypad area, making it easier to carry. Duga Hi Keys has two wireless connection methods, Bluetooth and 2.4G, which can be connected to 3 devices. There is an indium-plated knob on the top left side of the keyboard, and the rotary switch can be freely switched between Bluetooth 1, Bluetooth 2 and 2.4G . This way, everyday desktops, laptops, iPads, or other devices can share a single keyboard without having to reconnect every time you change devices. Compared with the traditional keycaps with concave design that fits the fingertips, this Hi Keys is the opposite, presenting a slightly raised curved surface, which is somewhat similar to the fluffy shape of bread, giving people a new input Experience, so that when you first get in touch with this new keyboard, you may accidentally touch it when typing quickly. However, after using it for a few days, I almost got used to it. The raised design is actually more in line with the ergonomic curve. It saves the step of pressing the wrist and lifting the code word, which will save more effort. In terms of operation, although Dujia Hi Keys is 84-bit, it also designs many convenient shortcut keys, such as pressing FN+F10 to mute the volume with one key, and FN+F11 and F12 to increase or decrease the volume without sliding the mouse to click. In addition, this keyboard has a backlight mode, which can be switched by the bright silver ball on the left side of the keyboard. Although there is only one kind of white light, there are 8 lighting effect modes to choose from, such as constant light, wave, breathing, starry, and ripple, and the brightness can be adjusted to meet the individual needs of different users. Individuals far away will basically not turn on the backlight mode in daily life, which will save more power. In terms of battery life, Duga Hi Keys has a built-in lithium battery. When the backlight is turned off, the battery life in Bluetooth mode can last up to 360 days. In 2.4G mode, it can also be used for about 200 days. It can be said to be very powerful; when the backlight mode is turned on, It can be used for up to 90 days, depending on personal usage. It should be noted that if the keyboard is not used for a long time, it is best to charge and maintain the battery regularly. As for the switch body, Dujia Hi Keys uses Kaihua’s new Turbo switch body. Although it is a domestic switch body, the user’s evaluation is still good. The large keys such as space and Enter are also designed with satellite switches, which is more stable. Yuanfang chose the silent red switch this time. Earlier, I liked the crackling sound of the code words on the green switch, but now I gradually like the lighter and quieter red switch, which makes it easier to concentrate. Thanks to its raised keycap design, Durga Hi Keys has a shorter stroke, faster triggering, and a very low sound, which is very suitable for people who like to be quiet. As a relatively unique new product, the performance of Dujia Hi Keys wireless mechanical keyboard is still remarkable. The overall design is simple and pleasing to the eye, highly recognizable, and the wireless connection method and 84-bit array are very good in reducing the occupied space. There is also a long battery life of up to 1 year and a variety of backlight modes with lighting effects, which greatly improve the user experience. Of course, it is a pity that it does not support hot swapping, but it is also flawed.

?The sharing of life is the multiplication of happiness?——Hi everyone, Xiaoxue is here! Recently, the person at home often travels on business, but the office is inseparable from the mechanical keyboard.

Right-hand man!" The price is also very affordable, suitable for beginners and low-budget friends. Taking advantage of the hot sale of the new model, the price is really beautiful. It is really worth buying it for more than 200 yuan!

Speaking of customized keyboards, everyone may think that the price is very expensive. To be honest, it is difficult to enter the threshold of customization without playing the keyboard to a certain extent, from kits to switches, from keycaps to wires, and even to Arrangement design, etc., customization can bring users personalized configuration and choices. Of course, this does not mean that buying a few keyboard parts and assembling them together is considered customized. High-end customized players are extremely particular about the choice of each accessory, and even build their own.... Let’s talk about it here, in fact, for users who have not entered the threshold of customization, it would be great if they can experience the fun of customization with a small budget. Recently, Rapoo has launched such a keyboard, which can hot-swap the switch body and customize all keys. This is the Rapoo V700DIY mechanical keyboard. The switch that matches with the Pennefather V700DIY currently offers a separate set of fast silver switches and spring white switches to choose from, while the main body of the Pennefather V700DIY has more optional switches. In addition to the above switches, there are also green switches and brown switches. select. It is believed that Rapoo will launch more separate shaft sets for users to choose soon. The shape design of this keyboard is generally tough, with a very narrow frame and an aluminum alloy panel on the top cover. In terms of shape, it is not an exaggerated mechanical keyboard, but more like an office keyboard. However, in terms of keyboard characteristics, it is not inferior to traditional gaming keyboards at all. About this, you will know when you look down. Items in the package: Rapoo V700DIY keyboard, cable, key puller and manual. When I took the keyboard out of the package, the exquisite workmanship immediately attracted me. The aluminum alloy cover was polished very well, with a very slight matte texture. The brushed metal LOGO on the upper right corner is very eye-catching, and the keycaps feel The touch feels great. After carefully reading the official announcement, I realized that it is made of PBT. This material has an excellent anti-grease effect. In terms of button arrangement, it is a traditional 104-size keyboard, and the addition of a small numeric keypad makes daily office work more convenient. There is a row of function keys in the upper right corner of the keyboard. The M key can switch between office mode and game mode. In office mode, 18 lighting effects can be switched through V1 key. In game mode, up to 19 lighting modes can be switched through V1 or driver software, and Each button can be individually set the light color. In addition, the light brightness and volume control can be quickly adjusted through the V2 key, and the function of the V3 key is a direct one-key mute switch. As for the metal scroll wheel key, it is based on the V2 key to define the function of lighting brightness or volume control. Near the center of the front side of the keyboard is the cable connection of the USB-C port. There is no fancy design here, such as any anti-falling grooves, it is not there, the main purpose is to allow users to Choose more third-party C-mount cables. The foot pads at the bottom of the keyboard are relatively thick. Although the feet can only be adjusted at a single angle, they are basically sufficient for most users. Let's take a look at the switch body of the keyboard. The one I bought is the Kuaiyin switch. Rapoo is one of the very few domestic manufacturers capable of self-developed switches, and this Kuaiyin switch is their latest masterpiece. The total stroke of the fast silver axis is 4mm, the trigger stroke is 1.3±0.5mm, and the trigger pressure is 45±10gf, which is a linear axis. As for the keycaps, the more expensive PBT two-color injection molding material is used. Personally, I prefer this kind of material keycaps. It is not easy to oil, and the touch is a little rough, but the texture and touch are believed to be good for those who have used it~ Especially for users who are prone to sweating, it is strongly recommended to try it! ! In terms of the feel of the quick silver switch, I think it is very similar to the "light" version of the red switch. First of all, it is linear, straight up and down, without paragraphs, and the rattling sound is relatively soft, and the command can be triggered easily. However, the sense of ease is simply amazing. The keycap can be triggered by sinking a little bit. I think this may be " The origin of the word "fast". Generally speaking, I think that if you are a red switch or brown switch user, it is not difficult to get started quickly with the silver switch. This kind of keyboard can bring a very smooth and silky experience whether playing games or text input. The shaft of the Rapoo V700DIY is a universal five-pin hot-swappable shaft, which can be easily removed by using the key puller included in the accessories. If you have five-leg shafts of brands such as Goto, Jiadalong, Kaihua, and TTC on hand, they are all universal. The game attributes of Rapoo V700DIY are not only reflected in the shaft body, as the saying goes, there is no gaming without lights~, so it will not fall naturally. The 104 keys of the Rapoo V700DIY can achieve 16.8 million color lighting effects, the brightness is moderate, and it will not be very dazzling in a dark environment. The actual viewing effect is still very good. This 104-key conflict-free design In addition to supporting single color customization, the driver also supports single function customization, and the playability is quite high! Rapoo V700DIY has shown a high level in terms of materials and workmanship, PBT keycap touch, shaft feel, RGB lighting effects and software drivers, although it is compared with professional customized keyboards. The customizable content is limited to keycaps, switches and cables, but it’s cost-effective! In the field of customized keyboards, if you really want to invest, there will be no less but more than those who play HIFI and cameras. If you want to try whether to step into the threshold of customized keyboards, then it will It's a good entry option.
