Hello everyone, I am Teacher Lin, and we meet again. The appearance and workmanship of the AC081 of the Heijue Light Krypton customized series and several other aluminum Tuotuo have attracted many fans. In addition, the price is affordable and the workmanship is good, which has attracted a lot of attention. At that time, I got started with AC081 and AC064, the only regret for AC081 is that this 75% matching theme aluminum tube adopts a wired single-mode configuration, even if it is equipped with an aviation plug-in cable, there is no three-mode support Still a little regretful. And the new AK816 pro mechanical keyboard released by Heijue this time, the appearance design is modified on the basis of AC081, and the shell is made of ABS injection molding. Compared with the AC081 made of all aluminum, the cost must be lowered, and of course the price has also dropped. down. However, the configuration has been upgraded. It retains the gasket structure commonly used in mid-to-high-end keyboards, a full set of sound-cancelling package, and RGB backlight to support music rhythm. In addition, it makes up for the shortcomings of the previous AC081. This model supports Bluetooth, Wireless and wired three-mode connection. Next, let us see if this customized AK816 pro is worth buying. Heijue’s AK816 pro keyboard adopts two colors, light color and dark color, with red and yellow function keys embellished, white is the theme of [Cosmic Adventure], black is the theme of [Rock Rhapsody], the original keycaps are two The pattern and color matching of this theme are still consistent. The layout of the Heijue AK816 pro is that 81 keys belong to 75% of the arrangement. This arrangement is more useful and retains the complete F key area and page turning keys. It is very friendly to our writers. The Gasket structure is used inside, and the upper and lower covers are provided with gaskets to support the positioning plate, and the feel will be softer than ordinary keyboards; it is equipped with Jiadalong's G silver pro 2.0 axis body, with a trigger force of 43g, which feels light and quick to trigger. The full set of poron cotton sound package (including sandwich cotton + shaft bottom pad + bottom cotton) installed inside this keyboard, the percussion sound sounds good. The keycap of Heijue AK816 pro adopts the sublimation PBT keycap with MDA height, which will not fade or oil after long-term use. Since there is no light transmission, the overall performance of light transmission is not very good. If you like the backlight to be brighter, you can use it with a set of light-transmitting keycaps. Heijue AK816 Pro keyboard adopts a Gasket mechanism to allow players to experience a better input experience. The gasket is made of silicone. The interior is equipped with a full set of Poron sandwich cotton, shaft pads and bottom cotton, allowing users to better experience more pure Typing sound and softer feel. At the same time, the Heijue AK816 Pro keyboard adopts a two-stage foot support, which can meet the needs of different people. Compared with the fixed-angle keyboard, it is more convenient and comfortable to use, even if it is not equipped with a palm rest. The Heijue AK816 Pro keyboard supports the switching of MAC and Windows configurations at the same time. The switching dial switch and the three-mode switching switch are all designed on the back of the keyboard, which is easy to identify and operate. The 2.4G receiver of the keyboard is set near the wired interface of the keyboard. It adopts adsorption storage. When not in use, it can be directly sucked up without worrying about losing it. From the experience of using the Heijue AK816 Pro keyboard in the past few days, the biggest feeling is that the performance of this keyboard is good. The three-mode design can be switched between desktops, tablets, and notebooks. It is very convenient to use. The main thing is that I didn't encounter any delay or disconnection in the wireless state, and the performance was stable. The G silver pro 2.0 paired with Heijue AK816 has strong rebound and just the key travel, which is suitable for my favorite handwriting. At the same time, the hot-swappable shaft seat of the Heijue AK816 Pro keyboard is made by Kaihua, which supports 3-pin and 5-pin shaft bodies. There is no need to worry about compatibility. It is very convenient to change the shaft by yourself later. Any shaft sold above will work. The Heijue AK816 Pro keyboard has a built-in 3000mAh battery, which guarantees the battery life of the keyboard. The official battery life score is 50 days with Bluetooth (turn off the backlight and use it for 5 hours a day), and the battery life is still very good. Due to the use of the ABS shell, the hand feeling is not as good as the previous AC081 series products, and the weight is much lighter. The weight of only 990g is still very light, and it is easy to carry when going out. However, it is really impossible to compare the feel of a plastic keyboard with an all-metal keyboard. The two focus on different aspects. Heijue AK816 Pro keyboard supports switching of 18 kinds of RGB backlight effects, and its appearance is online at night. The light color of a single button can also be changed through the driver, and it also supports the function that the light moves with the rhythm of the music. Everyone calls this light mode "music rhythm", which is quite interesting. Interested partners can go to their official website to download and set it. use. The blessing of the volume knob is also one of the features of this Heijue AK816 Pro keyboard. For me who works at the desk for a long time, a knob to adjust the volume can save me the time of dragging the volume bar with the mouse. Nothing is more convenient than this up. As for which color to choose for the AK816 pro keyboard, you can actually choose what you like. Cosmic Adventure adopts a light-colored design, and the ESC and space bar adopt a very cartoony design. And Rock Crazy is a lot more low-key and restrained. If it weren't for the embellishment of red buttons, it could really be described as unpretentious. For people who use computers a lot on a daily basis, the keyboard is partly a hobby in addition to the attributes of the tool. In fact, I use mechanical keyboards in the office and at home. The main reason is that it can be used with a notebook to achieve higher efficiency. At the same time, I also need to consider the quiet switch body. The best choice is to support the Gasket gasket structure. There are products that support DIY replacement of various shafts. At home, I mostly use small configurations, and 75% configurations are more suitable for me. The performance of this AK816 pro keyboard of Heijue is still remarkable in all aspects. MDA sublimation keycaps, RGB backlight, G silver Pro 2.0 shaft body, full-key hot-swappable, gasket structure, full set of noise reduction package, plus three-mode and adjustable foot support design, it is indeed a good choice at a price of more than 500 yuan.

It’s the annual Double Twelve Shopping Festival again. Although last month’s Double 11 Shopping Festival, many people bought their favorite good things. However, some people will definitely not get on the car in time, and when they come to their senses, the special offer has ended. But don't be discouraged, in order to make up for everyone's regrets, Double Twelve is coming soon. The most important thing about a mechanical keyboard is its switch body. As the core component of a mechanical keyboard, the Cherry MX mechanical switch is the representative of the mechanical switch. In addition, it also includes Cherry ML mechanical switches, ALPS mechanical switches, and Taiwan White switches. (very rare) and other three types of axes. Cherry MX mechanical switch is recognized as the most classic mechanical keyboard switch. The special feel and golden cross contacts make it double the quality. At the same time, the switch body of various colors has a great difference in feel, which can meet the various needs of different users. This time, I would like to chat with you about the original keyboard of Cherry, which is different for you and for different users, which one should you choose? Reason for recommendation: The Cherry MX8.0 mechanical keyboard uses the classic CherryMX mechanical switch and each switch is made by the original German factory. The CNC all-aluminum body is equipped with customized keycaps. One is not innovating for a high-quality typing experience. The white appearance is paired with crisp green shafts, allowing you to enjoy wonderful music while tapping. Ordinary green switches are not really suitable for text editors, but for gamers, the sense of confirmation triggered by the green switch is very good, with both a "click" sound and a clear sense of paragraphs. Match it with Cherry Assistant to customize your own color, and it is also a beautiful scenery when not in use. Double 12 Jingdong price starting from 1099 yuan can also be said to be very cost-effective. Recommended reason: As a 599 yuan cherry keyboard, the main keyboard of the student party. I think one of the highlights is the three-mode wireless mode, the innovative technology with a fast response of less than 1ms, the simultaneous connection of three devices, the 109 full key layout, and the MX red switch, whether it is a game or an office. The student party generally lives in the dormitory. When using the keyboard, the red switch will not make a more obvious sound like the green switch, which will affect others, and the red switch will not cause finger fatigue due to excessive pressure on the keys. Reason for recommendation: MX8.2 adopts the original MX shaft body of German CHERRY, and it is equipped with three connection modes, intelligent battery management, and aluminum storage box, which can be said to be very suitable for friends who play games. high. At the same time, the 20-day wireless battery life and multi-device switching are also very suitable for office white-collar workers who have meetings in various scenarios every day. Occasionally, they can also compete in games during office work. At the same time, the obsidian version also customizes the exclusive three-transparent keycaps with exclusive lighting effects, making it easy to find the corresponding keys. At the same time, for those who pursue quality, the prices of 1549 and 1599 are also acceptable. Whether it is office or game, it can be competent. Recommended reason: First of all, it is short, thin, and wireless. CHERRY LP2.1, and metal case LP6.1. It can be considered as two keyboards with different appearance and materials on the same platform. They all adopt a compact 68-key layout scheme, equipped with LP short switches, and match a set of short keycaps to achieve a relatively slim design language. At the same time, it also has the advantage that it is relatively lightweight and very easy to carry. The LP6.1 with a metal case will be heavier. In terms of appearance, the LP2.1 with a plastic shell has rubber feet, while the LP6.1 with an all-aluminum body is a traditional tripod. The shell thickness and inclination angle are basically the same. There is a little difference in appearance, LP6.1 sinks slightly, the frame is higher than the liner, and there is a "waistline", which naturally looks better and distinguishes high and low positioning. Moreover, the aluminum body, in order to reduce the signal barrier, specially made a plastic cover nameplate on the front frame. In terms of details, the LP2.1 plastic shell is treated with imitation marble snowflake texture, while the LP6.1 is anodized. Match the keycaps with corresponding colors. The 68-key LP series can be said to be CHERRY's ultra-thin mechanical keyboards that are wireless, portable, and multi-platform compatible in the true sense. The first color matching is also quite rich. Compared with the same type of keyboard, its biggest feature is the CAWT wireless solution. It is an office body, but it has game-level wireless performance. At the same time, the price of version 2.1 is 699 yuan, and the price of version 6.1 is 1099 yuan. This price is also very sincere. Reason for recommendation: Today, Cherry, the leader of the mechanical keyboard industry, has also launched the entry-level full-key mechanical keyboard KC200 MX series for office scenarios. The price has dropped but it still maintains the consistent high-quality features. The main selling point of the Cherry KC200 MX series is the Cherry MX shaft body + colorful color matching design. There are four colors of bronze, orange gray, blue and white color matching and pink color matching for users to choose from. At the same time, the price starting from 379 on Double Twelve is also very fragrant. up. For beauties, it is absolutely irresistible! Of course, with a good keyboard, it’s not too much to add a good mouse. I recommend the Cherry MW5180 wireless Bluetooth mouse with a price of 99 yuan. It supports 2.4G wireless and Bluetooth dual-mode connection. The Bluetooth mode can also connect three devices at the same time. It is equipped with PixArt. High-precision optical tracking sensor, with 1200DPI, battery life up to 300 days, and the surface of the mouse is covered with a magnetic cover, which is convenient for users to match. The second half is designed with a certain radian to ensure that it can fit the palm better, and it is still not tired after long-term use. CHERRY MW5180 uses silicone rollers, irregular non-slip design on the side, and is equipped with multi-function indicator lights. The weight of the body is only 76g, which is light and easy to carry. Everything that has been used is good! Reasons for recommendation CHERRY DW2300 keyboard and mouse set is a new product launched by CHERRY in the first quarter of 2022. It focuses on wireless low-latency, soft office, exquisite and full-featured office keyboard and mouse set. Using advanced 2.4G wireless connection technology, a receiver is connected to the keyboard and mouse at the same time. The classic chocolate key, with its unique curved surface and rounded keycaps, fits your fingers and provides comfortable fingertip feedback. The full-size key area has 8 shortcut keys with customizable functions. Lightweight mouse, only 70g without battery. The keyboard and mouse are designed with light-tone keys to effectively reduce noise and not disturb people. Low power consumption and long battery life. At the same time, the DW2300 adopts a retro design. The appearance of this keyboard can be said to be a direct blow to dimensionality reduction on the same type of office keyboard. The keys use a complete 104 keys, and there are independent numbers on the right. Keyboard, so it is still very comfortable for office parties. The edge transition of the keyboard is handled very well, and there will be no slight feeling when the palm is placed on it. There is also a fixed long foot pad at the bottom as a heightening foot support, which can improve the comfort of the wrist when typing and avoid fatigue after long-term use. The connection method adopts a 2.4G wireless connection method. The keyboard and mouse share the same receiver, which is very convenient for connecting to computers and other devices. Since I have been tossing around with digital products, I have handled a lot of keyboards, but not many left in the end. I have been superstitious about "powerful miracles", and I have also tried "domestic electrostatic capacitors". It is not whether the keyboard is good or bad, but I have been looking for it. A keyboard that suits you. Now the main keyboard in my hand is the 3494 red with side-engraved keycaps replaced, and it has been used for a long time. Friends who have touched it are full of praise for its feel. I believe that after continuous exploration, everyone will find a good keyboard that suits them. This Double Twelve, just bravely chop your hands!

Everyone roar, the jellyfish meets you again. Speaking of ikbc, if you have a certain understanding of mechanical keyboards, then I believe you must not be unfamiliar with this brand. As an old keyboard brand that has been focusing on mechanical keyboards for more than ten years, compared with other keyboard brands, ikbc has high cost performance and fast innovation speed. It has been recognized by many players. Some time ago, ikbc launched the new 98% Gundam co-branded keyboard Z98. This keyboard adopts the theme color matching of the Earth Federation Army RX-78-2 Gundam, and the Gundam logo and various symbols are printed on the keycaps. At the same time, this The keyboard is also ikbc's first 98% equipped mechanical keyboard. The price is less than 300 yuan. In terms of packaging, the ikbc Z98 mechanical keyboard is packaged in a simple pure white package, with only the ikbc brand LOGO in the middle, and a ikbc X GUNDAM joint sticker on the upper left corner of the package. Open the package, in addition to the mechanical keyboard itself, a key puller is also included. Take out the keyboard, the overall texture of the keyboard is very good, and it does not lose the materials used in many thousand-yuan keyboards. In terms of keyboard size: 383 X 140 X 44mm, with a total weight of 1148g. The 98% keyboard does not need much introduction, it can meet all usage scenarios, whether it is daily office input or playing games, it is perfect. Compared with the full key 108 arrangement, there are fewer function keys in the middle, and the number keypad is retained, achieving the coexistence of compactness and practicality. Gundam's classic blue, white, and red colors are well reflected on this keyboard. The keycap adopts two-color injection molded PBT keycaps. The overall workmanship of the keycaps is fine, and there are no problems such as spouts and burrs. It is not easy to be stained with fingerprints and oil, and it is better in wear resistance, and it is not easy to scratch. The surface has a slightly concave design, which has a certain sense of wrapping, and the typing feels great. The keyboard is full of Gundam elements, the ESC key is printed with a Q version of the Gundam head, and the Enter key and the space bar also have the logos of the E.F.S.F Federal Army and GUMDAM. The keyboard adopts the domestic Longhua customized red switch and the crater design, which is not inferior to the original Cherry switch in terms of feel. I have to say that the progress of the domestic switch in the past two years is still very obvious. As a jack-of-all-trades switch, the red switch is generally considered moderate among mechanical switches. It is light and soft to use straight up and down, and the elastic feedback is also clear. To put it simply, the feeling of use is: the difference between the tea switch and the green switch has a sense of paragraph, which is lighter and instant; and there is no disturbing rattling sound of the mechanical keyboard, no matter whether it is used in the dormitory or the office, it will not affect others. At the same time Although the red switch feels lighter, compared with the false triggering of the silver switch, there is no need to worry about the red switch, especially for jellyfish who usually need a lot of typing and develop the habit of touch typing, basically there is no false triggering Case. The keyboard adopts a full-key non-impact design, and the large key position adopts a satellite-axis design, which can better restore the feel of the axis keys, and at the same time avoid the uncomfortable experience of looseness when typing on the keyboard. With such a configuration at this price, it is also very cost-effective. High. The keyboard adopts a single-mode wired connection, and the three-way wire slot on the back can better manage the wires and ensure the cleanliness of the desktop. The one-piece foot support can make the keyboard have a certain height, and we can adjust it according to the usage habits. I have to say that the cost performance depends on ikbc, solid workmanship, excellent appearance design, and the genuine joint name with Gundam, which can be realized at a price of less than 300 yuan. ikbc Z98 is definitely one of the very worthwhile peripherals for GUNDAM fans. !
