Note: The rewritten article maintains the same word count as the original, and the theme of troubleshooting Logitech wireless keyboards is consistently followed.

I believe that players who often play with peripherals must be familiar with the brand of Aishitou. It has always been known for its cost-effectiveness, and its reputation among players is also very good. Recently, the AI ​​Stone AL87 series has added a new member, which is the AI ​​Stone AL87 Pro three-mode mechanical keyboard. So how about its experience, please follow my footsteps to reveal it together!

PS: The experience and skills of using this keyboard in the article are marked in bold font. If you want to start with Ai Shishi's AL87 Pro three-mode mechanical keyboard, don't miss the tips! I believe it can be helpful to you!

The appearance design of the AI ​​Stone AL87 Pro mechanical keyboard is quite simple, and its appearance is also very high. mechanical silver color CNC aluminum alloy body , the surface passes through Anodizing process treatment ， silky touch . While ensuring the firmness of the keyboard body, it also brings a better visual effect. Although the 87-key design is compact, it can fully free up the desktop space and leave more movable range for the mouse. Of course, it is far more than these that attract me!

Currently in the market, the most common keyboards used by players are mainly composed of full-size and TKL keyboards, which are keyboards with number pads and keyboards without number pads. Among them, TKL is the most popular, because in the usage habits of most users, the number keypad on the right may not be used. The AI ​​Stone AL87 Pro mechanical keyboard is more like a TKL keyboard. Under the compact structure, it is not too inconvenient to use. Moreover, the keyboard has quite a lot of combination key functions, and shortcut combination key icons are also engraved on the keycaps, which is convenient for users to use.

In order to meet the needs of different users, the AI ​​Stone AL87 Pro mechanical keyboard has Support 2.4G wireless, Bluetooth 5.0 and wired connection . First of all, in terms of wireless, through the USB receiver that comes with the keyboard, it can be compatible with most PC, Mac, iOS, Android and other devices. For the connected device without USB interface, it can also be connected via Bluetooth. It is also very convenient to use it with a laptop or tablet when going out.

The wireless switch is located on the left side of the fuselage, select "ON" to turn on the wireless, and select "OFF" to turn on the wired.

The wireless receiver is placed on the wired wire, and it should be kept carefully for daily use. It is also worth mentioning that the wireless receiver is equipped with a sleep function. If you connect the wireless receiver and wired cables to the computer at the same time in daily use, you need to switch the connection mode by yourself. In the case of Lian, this needs to be paid attention to.

The wireless connection of the AI ​​Stone AL87 Pro mechanical keyboard is stable in daily use, and there is basically no disconnection. benefited from 3800mAh high capacity battery , when the backlight is turned off, it can provide up to about 960 hours of battery life, and it can also provide about 168 hours of battery life with the backlight turned on, which is enough to meet the daily use of users.

In addition to wireless Bluetooth, Ai Shishi AL87 Pro mechanical keyboard Support wired mode , and adopted the Machine line separation design , The cable material is flexible and soft, and it is equipped with an anti-magnetic ring for efficient use of the keyboard. With the USB Type-C interface, it can conveniently and quickly replenish the power of the keyboard, and the convenience performance is still good. The connection socket is built-in, and the advantage of this design is that even if the wire is accidentally touched, it will not be torn off or loosened at once. In addition, in addition to the original factory line of Ai Shishi, it also Support the use of aviation plug-in lines 。

Looking from the side of the keyboard, you can find that the Ai Shishi AL87 Pro mechanical keyboard has a slightly inclined design. It naturally forms a 5° angle with the desktop. With the stepped keycap curvature, you will not be tired when typing for a long time, and the hand feels better. Lightweight, typing on the keyboard will also appear lighter.

The back of the Ai Stone AL87 Pro mechanical keyboard is a whole piece of aluminum plate structure, equipped with foot supports, which is more flexible in use. Four round anti-slip pads (there are also anti-slip pads on the feet) can make the keyboard stable on the desktop, so that the keyboard will not move when typing text quickly.

In terms of accessories, the AI ​​Stone AL87 Pro mechanical keyboard comes with the keyboard body, USB Type-C cable, and warranty card. This time there is no manual included, but Ai Stone provides manuals online , including the operation guide of various peripherals under Ai Shitou, interested players can click on the portal on the right to enter and view. (online manual portal).

Ai Shishi AL87 Pro mechanical keyboard has three options of red switch, brown switch and green switch in terms of the switch body, and it is still a customized switch body of Ai Stone. The shaft body used in this AI stone AL87 Pro mechanical keyboard is Ai Stone V3 Axis , Compared with the Ai Shishi V2 shaft body, the performance in terms of feel can be said to have been significantly improved. It not only optimizes the feel, but also improves the durability, and even better, it reduces the knocking noise and shaking. Furthermore, with the built-in three-stage sound-absorbing cotton, it has made a qualitative leap in its overall performance.

In addition, Ai Shishi AL87 Pro mechanical keyboard supports 16.8 million color RGB backlight effects , also in the driver software 20 preset lighting effects . After connecting the device, the lights are very dazzling, and the e-sports atmosphere is instantly bursting.

Big keys use Satellite Shaft Design , although the overall adjustment level is much stronger than before, and because the silicone strip of the space bar makes its percussion sound more pure, without the trouble of steel wire sound or other noises, the consistency of the feel still needs to be improved.

The keycap of the Ai Stone AL87 Pro mechanical keyboard is made of ABS material with two-color injection molding process. It is a closed character. While improving the overall aesthetics of the keyboard, the characters are also clearer and wear-resistant.

We can use the official driver software provided by Ai Stone (IROK Assistant) , to configure the keyboard. The functions of the software interface are clear and clear, and the operation functions are quite rich. Whether it is the definition of key functions or the setting of lighting effects, it is very convenient.

After the driver software is installed, an icon of Aishitou LOGO will be generated on the desktop. When the mouse is moved to the icon, a multi-layer tool icon will appear, including Aishitou driver software, Aishitou personal customization, personal center, and new shortcut software Open the settings.

In the action settings of the driver software, there are setting items for buttons, macros, and multimedia, which can add more convenience to users.

There are more than 20 preset lighting effects in the lighting effect setting. The lighting effect style is unique and worth playing. Of course, we can also set the lighting effect by ourselves.

It is worth mentioning that in the lighting effect setting option, we need to pull the brightness to full brightness, and it is off by default, otherwise we will not be able to see the effect when switching the lighting effect.

In addition, the driver software also provides Ai Shishi personal customization function, providing a variety of PBT keycaps for players to choose, which also makes this Ai Shishi AL87 Pro mechanical keyboard more playable.

Although the official product page of Ai Shishi does not indicate whether it supports full-key rollover, but through the actual measurement of the Keyboard Test Utility software, there is no key that is actually pressed but not sent, so it can be seen that it does support full-key rollover , which is great for text input and gaming.

In terms of comprehensive experience, the overall workmanship of the Ai Stone AL87 Pro mechanical keyboard is excellent. The all-aluminum shell and the white panel cover are quite simple. It is also a good decoration on the table. For table players, this one is good. Yes, and there are two styles of black and white for players to choose from. Moreover, Ai Stone AL87 Pro combines high-endurance three-mode connection, 16.8 million color RGB lighting effects, full-key hot-swappable, high-quality mechanical shaft, etc. You can experience such a delicate aluminum lump for more than 400 yuan, I think it is very worth it!

I believe that friends who learned computers with 7080 have experienced the era of tens of thousands of codes in the early years. The codes mentioned here are not codes but input methods. The earliest Chinese character input method is the telegraph code in the late 1970s. Four digits from 0 to 9 are combined to form a Chinese character, also known as the area code. The early bank commissioners need to learn, which can be said to be the input method with the highest recognition rate. Since 1981, we have Pinyin input method and Wangma Wubi input method, and then Shuangpin, Jianbi code, Xinyin code, phenotype code, Wan code, Zheng code, and natural code. In the end, there are basically only two input methods left: Pinyin and Wubi, which are the masters of phonetic code and graphic code respectively. Among them, Wubi is suitable for accurate input when the pronunciation is uncertain; Pinyin is more suitable for association, phrase or even entire sentence input.

The mechanical keyboard that many digital hipsters are talking about now has actually experienced an era of tens of thousands of axes. In the earliest period, the German cherry axes almost dominated the rivers and lakes. However, due to the surge in demand and the pirate ship's attempt to monopolize the cherry axes, the incident of "one gasification and three cleanups" of the axis body was intensified.

Of course, it’s just nonsense, but because of the problem of monopolizing the supply of goods, Razer and Kaihua cooperated to produce a green Razer shaft. Later, Razer and Kaihua went to their own wonderful things; Logitech and Omron Cooperation, to come up with an Omron G-axis that is not compatible with MX-axis keycaps, and the hatchback eventually dislikes it; the last one is the innovative optical axis developed by the domestic manufacturer Ruiyi Shark.

Naturally, the Razer switch is exclusively for Razer, the Omron switch is almost only used by Logitech, and the optical switch is basically used by both domestic and foreign brands.

Basically, the current axis body is the same as the input method, basically there are two poles left. The two poles of the Chinese input method are Pinyin and Wubi, and the two poles of the shaft body are MX-like shafts, that is, the shaft body uses metal deformation as the trigger principle, including cherries, Kaihua, TTC, and Jiadalong, which imitate cherries, and other domestic excellent switch manufacturers. The other pole is the optical axis dominated by the Raywing Shark.

Let’s take a look at the triggering principle of the MX axis first. The MX axis is full of things with a metal structure, and the signal is generated by pressing the keycap. The keycap introduces pressure into the interior through the axis core, so that the internal metal sheet generates Deformation produces a signal.

As for the optical axis, it is obvious that the signal is generated by cutting off or turning on the optical signal. Although there are also mechanical components, the dependence on metal characteristics is greatly reduced.

Metal oxidation and metal fatigue are unavoidable characteristics of metals.

Friends who have used mechanical keyboards with pluggable shafts know that our common shafts have two pins, and these two pins correspond to the moving film and the static film. The moving piece is responsible for deformation to generate signals, while the static piece is the signal conduction. Obviously, the moving piece is more affected by the metal characteristics. Simply put, if the moving piece is useless, the shaft will be useless.

In contrast, the dependence of the optical axis on the characteristics of the metal is greatly reduced. Compared with metal sheets, springs are much more difficult to damage, and the MX shaft also has springs.

Due to the substantial improvement of the structure, the optical axis has more advantages that the MX axis does not have. For example, better waterproof and dustproof performance, quieter, lifespan of 100 million times, and 0.2ms response speed.

Magnetic power may not be too well-known in the consumer market, but it is a frequent visitor to the Internet cafe industry and belongs to a brand with high cost performance. CK500 is a product with full optical axis. It adopts rainbow mixed light backlight and comes with a huge hand rest. It is a bit retro in appearance, but it is quite good in terms of user experience.

The full key has no impact, and the metal cover is a floating keycap, which is a quite satisfactory product.

In terms of brands that use more optical axes, Dimo ​​is also very representative. Almost all models of Dimo ​​mechanical keyboards are available in cherry switch and optical switch versions.

Interestingly, in 2018, Dimo ​​also carried out Dimo ​​2.0 activities. Specifically, many of its mechanical keyboards can provide a two-year warranty, but most of them are mechanical keyboards with optical axes. This is because the optical axis is inherently better than the MX axis in terms of lifespan and waterproof and dustproof.

Dimo F1 adopts the mainstream compact and simple design, and the four frames are all ultra-narrow frames, which not only makes it more tidy and capable, but also saves a lot of space on the desktop.

You know, many professional FPS e-sports masters in the early days put their keyboards at an angle. On the one hand, the tables in early Internet cafes were too small, and on the other hand, it was to free up more space for the right hand to control the gaming mouse.

104-key full keyboard, and 104-key full-key programmable. That is to say, each button can be macro defined. You must know that some FPS games now have a lot of buttons, and when we play games, only the left hand controls the keyboard. If you want to optimize the buttons, customizing is still very interesting.

In terms of backlight, the keyboard area adopts the mainstream rainbow mixed light, and there are RGB light strips on the side, which is cool but not directly stimulating, affecting input and operation.

Speaking of the optical axis, the most representative one is of course the ghost of the bloody hand. At that time, Bloody Ghost launched the optical axis mechanical keyboard and optical micro-movement gaming mouse with great momentum.

The B760 uses the second-generation optical axis. Compared with the first-generation, it has a clear sense of paragraph and crisp feedback sound. There are actually two versions of the optical switch, one is the clang version with a crisp sound, which is similar to the classic MX blue switch; the other is the silent soft version, which is similar to the classic MX brown switch. However, what is seen on the market is basically the former, and the latter is basically not seen.

In fact, the interval between the second-generation optical axis and the first-generation is very short. It can be said that the second-generation optical axis is basically the second-generation optical axis on the market.

The popularity of mechanical keyboards with optical axis and compact design is essentially more suitable for Internet cafes and high-intensity gamers in terms of lifespan and feel.

The optical axis mechanical keyboard product line of Bloody Ghost can be said to be the most comprehensive. The first first-generation optical axis mechanical keyboard, the first second-generation optical axis mechanical keyboard, and the first third-generation optical axis mechanical keyboard are all from Blood hand ghost. As early as 2018, Bloody Ghost launched the third-generation mechanical keyboard B975 with optical switches.

Interestingly, after launching the B975 third-generation optical switch mechanical keyboard, Bloody Ghost launched the B770 second-generation optical switch product.

At present, the second-generation optical axis and the third-generation optical axis coexist in the market, and the latter is a mid-to-high-end product.

In terms of appearance, the most significant change of the third-generation optical axis is that an additional metal balance bar is added to the axis body to ensure that each press is straight up and down, thereby maintaining the consistency of the feel.

The feel and response speed have not changed much, but the stroke is slightly longer than that of the second-generation optical axis.

The B975 also provides a detachable hand rest, but due to the relatively early release time, this hand rest is not magnetic.

Among foreign brands, Razer also has mechanical keyboards with optical axes. Light Factory's optical axis mechanical keyboard is divided into segment optical axis and linear optical axis, among which the purple one is the segment axis, and the red one is the linear axis.

Purple axis (paragraph): optical trigger, total stroke: 3.5mm, trigger stroke: 1.5mm, trigger pressure: 45g

Red axis (linear): optical trigger, total stroke: 3.5mm, trigger stroke: 1.2mm, trigger pressure: 48g

There is a clear difference in the feel of the two, but this is a more subjective issue. Basically, friends who are used to the paragraph axis will need a certain period of adaptation when they first come into contact with the linear axis.

The keyboard uses a set of UV-coated ABS keycaps, which are warm to the touch. But easier to oil. The font is the standard font for Razer’s new generation of keyboards. Compared with the previous non-mainstream style, this set of fonts is more restrained and slender, and the keycaps have a good light transmission effect.

The Hunting Light Spider Elite Edition also has a detachable hand rest, and the hand rest feels good on the skin. The multi-function media key can play a lot of fun with Leiyun. The multi-media knob uses a mechanical encoder with a damping feel, which feels good in the hand. The upper cover adopts a metal panel with metallic paint and fine matte texture, which feels good and heavy.

The era of mechanical keyboards is no longer dominated by foreign companies. Thanks to the rapid development of domestic switch factories, we not only have substitutes but also entered the overtaking lane. Compared with MX-like switches, optical switches are more innovative. At the same time, many friends have doubts about this. Is the optical switch a mechanical switch? From the perspective of metal structure, the optical shaft has indeed subverted the tradition, but from the broad physical definition, the optical shaft still belongs to the category of mechanical structure.

The commercially available optical switch mechanical keyboard has long been the fifth option after black tea and black. Compared with the classic MX switch, the optical switch's lifespan and advantages in waterproof and dustproof also give us more choices.

Keyboards and mice are currently the number one productivity tool on the market. No work can be done without a computer, and any game requires a keyboard and mouse. As long as the computer is turned on, the keyboard and mouse are active. The more active the computer, the more handsome it is. If even the keyboard and mouse are not often pulled out and moved, what is the PC? They all complement each other. In my keyboard army, I only love playing keys and 87 keys. This kind of 75-key arrangement of the main operation area + direction area, I recently won the Heijue AK873 three-mode 87-key mechanical keyboard, let’s take a look together.

[unpacking]

The packaging is packaged in a carton box with a pure white color scheme, the edge is painted with the brand Heijue, the product name is AK873, and the appearance frame diagram of the keyboard. This keyboard is also a cooperation model of the Actis Vocational Youth Training Base. The flexibility of the three-mode connection is guaranteed, and the detailed keyboard parameters and manufacturer information are on the back.

▲First of all, I would like to like the inner packaging of Heijue. The dust cover, plastic thin, and keyboard accessory partitions are all designed. The accessories include the keyboard host, data cable, shaft puller, six spare mac keycaps, four second Daishanlan shaft, manual, warranty card.

▲What is more interesting about this Heijue AK873 is that the keycap can be embedded or suspended, that is to say, its panel can be disassembled, which means that the dust in the gap between the shaft body after long-term use is very easy to clean, and I personally prefer suspension The unique design, firstly, the effective diffusion of the RGB light, which is very beautiful at night, and secondly, it is easy to clean.

▲The cover plate of the mask is designed in a magnetic way, which is very convenient to disassemble and install, and can be disassembled and assembled manually. The overall layout adopts 87 keys, bluetooth, 2.4G, type-c wired three-mode connection, Daybreak White/Extreme Day Gray color matching, I bought Daybreak White, which is very clean and simple.

▲The design on the back is relatively rich, integrating the keyboard switch key, USB2.4G receiver card slot, one-piece support rod, rubber feet at the four corners, everything you need, and the keyboard is made of ABS material as a whole. And also designed a waterproof diversion opening.

▲The keycaps are designed with a classic silky large keycap feel, MDA height PBT sublimation keycaps, and the surface of the keycaps has a matte texture, which is very comfortable for fingers to touch. It can basically meet the operating height of most people's wrists. Built-in 2500mAh lithium battery, according to experience, it can meet up to 100 hours of battery life.

▲ In terms of the switch body, Heijue uses two self-developed hot-swappable second-generation Shanlan switches/Biluo switches. My model is a linear Shanlan switch, and the Biluo switch is a tea switch. The trigger pressure of the Shanlan switch is about 45g, and the trigger stroke is 2mm. The total stroke is 4mm, the full-axis transparent frame has excellent light transmittance, and supports 3-pin and 5-pin light positions. The keycap is made of monochrome injection molded PBT material, which has good oil resistance. The keyboard structure is currently a very mainstream level, including: shaft body, positioning plate, interlayer cotton, pad under the shaft, PCB board, shaft seat pad, bottom cotton, and bottom shell.

▲Heijue AK873 adopts the Bluetooth 5.0 connection protocol. The three-mode connection is very suitable for the current fruitbook. It will consume less energy than 2.4G. The Bluetooth 5.0 technology is still very mature, with an effective range of 10 meters, stable connection, and anti-interference strong ability.

▲ There are 18 kinds of lighting effects on board when leaving the factory, which is quite enough, including rainbow flow, breathing, constant light, trigger and other modes. You can also adjust the direction, speed, and brightness of the light, all using the combination of FN + adjustment , This is good, there is no need to download the PC-side driver tediously, of course, if you want to set more lighting modes or macro buttons, you can also download it.

▲The Heijue AK873's various bottom cotton, shaft pads and other configurations make the knocking noise of the shaft body very low, basically not exceeding 70dB, and the knocking sound of the shaft body is very similar to the sound of mahjong, which is not disturbing to the people, and it is quite Nice to hear. The overall height does not need to be supported by a support rod, and the height of the keys is just right.

▲If you want to live a decent life, the game must be fun. In fact, there is no need to talk about the full key and no punch. Mechanical keyboards basically have everything. But there is still a screen to go up, the full key has no red, and the performance is good, you can play fighting games such as Tekken and KOF.

▲ LOL incoming materials, after dinner, I have to use two for daily work, LOL actually has higher requirements for the mouse, the keyboard is basically just a few buttons, if you use it for a long time, those few buttons will inevitably be oily, this is normal, professional players , the keyboard is bright. The overall output trigger is sensitive, and the key positions are accurate and there is no false touch. I still prefer this kind of large keycap, with zero sense delay, but the trigger pressure is a little bit high, just get used to it.

▲The porting of God of War 4 has brought me too much fun. This kind of experience of hitting the face with circles is actually the most suitable controller, but without a controller, I can use the keyboard. The main thing is to move, the sense of position is very accurate, it is inevitable not to operate violently during the game, the GASKET structure of the keyboard also exerts a soft bounce effect, there is no hard feeling like fingers sticking to the table every time you press, The soft bounce is very comfortable.

【Summarize】

▲Heijue AK873 has a net weight of 1045g. Although it is an ABS outer frame, the internal stacking proves everything. This weight is not too much, and I am very satisfied.

To make a summary of this keyboard, the effect of sandwich cotton + shaft pad + bottom cotton three-layer sound-absorbing cotton is obvious, and the sound-cancelling effect of the linear axis is better. It has a good percussion feeling, and it can be used for games, entertainment, and daily office work. There is also a Bilu paragraph switch that is optional. The full-key hot-swappable switch can be used by DIY to replace any other switch body later. The battery is 2500mAh, and the battery life is not bad. I prefer it Love that 10000mAh keyboard. I like the detachable outer cover the most, it is very convenient for cleaning in the future. The Bluetooth and wireless performance configurations are good, and the price is not expensive. It is recommended to buy children's shoes with a keyboard to try, and there are plenty of materials.
