The mechanical keyboard I bought before was a 68-type keyboard without a numeric keypad area, so I needed an unlimited keypad to use it. Considering the meager USB ports of the notebook, I finally bought Hangshi’s Bluetooth keypad at JD.com for 50. In fact, there were several colors, but in the end I bought the dream dark color. After I got it, I felt that it was okay. It’s not ugly but it’s not good-looking either. The back is the standard appearance of cheap electronic products. There was originally a foot pad on it, but I don’t know when it fell off, but anyway, I usually use it on a tilted stand. It doesn’t matter if it’s gone. The Bluetooth connection is very fast, and it also supports Bluetooth 5.0. However, due to the fast sleep in normal use, occasionally there will be a slow wake-up problem. It takes a while to react, but there will be no problem in normal use, that is, click just a little delay The feel is exactly the feel of Zhengcang's membrane keyboard. As a numeric keypad, using a round keycap will not have any negative problems. It will not be as difficult to use as the previous round keycap K380, but the feel is definitely a mechanical keyboard commonly used in peacetime. no comparison This is the cheapest bluetooth numeric keypad I have found. It is quite enough to use. If you just need a numeric keypad but do not use it often, this is very good. If you are an accountant who often uses a numeric keypad, it is still more Let's spend some money and buy a good one.

Recently, I feel that the desk is too messy. I want to tidy up the desk and make the desktop more beautiful and concise. The 108-key keyboard used before takes up too much space, and after actual use, the usage rate of the number keys next to it is also very low, just in time. On Double Eleven, I bought this hot-swappable three-mode mechanical keyboard with 65% configuration and 69 keys on the Internet. It is the Heijue K690T PRO, a small keyboard with both appearance and strength. Speaking of Heijue, friends who often look at keyboards should be familiar with it. The brand founded in 2009 has relatively high cost performance. Package The packaging of the Heijue K690T PRO Bluetooth three-mode mechanical keyboard is still very simple. The front is the main picture of the keyboard and the specific model. The logo of the partner of the League of Legends professional youth training base in the upper left corner is still very eye-catching. This shows that Heijue His strength has been recognized by professional players. After opening the box, you can see the main body of the keyboard. Let’s put it aside first. In addition to the main body of the keyboard, there are still a lot of accessories, including TYPE-C cable, 2.4G receiver, key puller, shaft puller, and instructions. Because it is a hot-swappable mechanical keyboard with replaceable shafts, this time Heijue K690T Pro presented a key puller and a shaft puller, which is very considerate (I don’t know if it was installed more, I have a total of 2 of this one) key puller 2 shaft pullers). Exterior Heijue K690T PRO provides two color choices, the color matching of the two colors is very small and fresh, and the name is also small and fresh, mint vanilla and lemon wafer. I chose lemon wafers this time. The overall color combination is white and yellow. The color saturation is also very low, which visually gives people a sense of elegance and freshness. The layout of the key positions adopts a layout of 69 keys, so that the ESC key and the mode switching key are in a row on the top, the brand LOGO is in the middle of the two keys, and the indicator light is on the left of the mode switching key. So many elements are designed in an orderly manner. There is a sense of order and it also looks very refined. Thanks to the 69-key layout, the keyboard maintains a compact body, which is very friendly to friends who travel frequently. The keycap of Heijue K690T PRO adopts PBT double injection molding process, which has a great touch, clear font, very wear-resistant and not easy to oil; there are four huge anti-slip pads on the bottom of the keyboard, which is believed to be completely stable when placed on the table. Guaranteed. Shaft The shaft body of Heijue K690T PRO is Heijue’s own Shanlan switch, which is made of PC material as a whole, and high-strength springs are used to increase stability. Some large keys are also equipped with Heijue’s carefully adjusted satellite switches to maintain Consistency of feel. I have been using it for a period of time. Not only does it feel very good, but the typing sound is also very pure. This is due to the double-layer cotton inside, which avoids hard collisions inside the keyboard when typing, and makes the overall keys feel better. , The sound of typing is also more pure. The key position adopts the layout of high and low keys, which is in line with ergonomics. It looks like an arc from the side, which can perfectly fit the movement trajectory of fingers when tapping up and down, making the hand feel more comfortable and not tired after playing for a long time. hot swap As a hot-swappable keyboard, Heijue K690T PRO adopts Kaihua hot-swappable shaft seat, which can support most of the three-legged and five-legged shafts on the market, plus the attached shaft puller, for those who like DIY Friends can transform according to their own aesthetics. connect There are three connection methods of the Heijue K690T PRO keyboard, wireless 2.4G connection, multi-channel Bluetooth 5.0 connection and Type-C data cable connection. The mode switch button in the upper right corner can freely switch between the three connection methods. The multi-channel Bluetooth connection allows one keyboard to connect to three devices such as a mobile phone, a tablet, and a computer at the same time, and can seamlessly switch between the three devices during use. backlight For a gaming mechanical keyboard, how can there be less cool RGB, but for people like me who have seen a lot of RGB lighting effects, I still like the pure color backlight of blue light or white light, and the lighting settings can also be downloaded from the official website. The driver can make more personalized settings for the keyboard, not only can adjust the light color or mode, but also can design the macro keys. battery life Heijue K690T PRO has a built-in large 2000 mAh battery. In wireless mode, turn on the RGB lighting effect and last for about 15 hours. The business trip party does not have to worry about the battery life at all. The TYPE-C data cable is used for charging. It’s ok, many mobile phones now use C-port data cables, and charging is also very convenient. Summarize On the whole, the Heijue K690T PRO still has many bright spots, such as good looks, comfortable keyboard feel, multi-device connection, and long battery life. These highlights still impress me very much, and this keyboard really fits well on the table. It is simple and elegant at the same time. I plan to use it for a long time in the future. If you are also impressed by its highlights, you might as well hurry up Get one and try it out.

A few nights ago, in a second-hand group, I saw someone hanging a broken keyboard. Everyone probably thought it was not in good condition, and no one asked for the price. I went up and asked him, 10 yuan can't be paid out, and this brother probably was really unhappy with it, so he agreed. In the morning of the next day, I went to hand it in offline in a hurry, and took a photo of it when I got it. It was extremely dirty. But fortunately, we had the foresight and brought gloves. Hair, water stains, oil stains... The first thing I did when I went back was to remove all the keycaps and throw them in the trash. They were really dirty to death, with all kinds of organic stains on them. Then there are all kinds of things on the top and bottom of the cover. Take a shoe brush and add laundry detergent, and brush it for a minute or two before I feel that it is a pass. Finally, the shell was brushed again, and the appearance renovation was completed at the beginning. Successful blood sacrifice while brushing After that, remove the moisture on the shaft body and PCB. The most basic thing is to shake it first and then pat it. It lasted for about half an hour. I feel that it is almost done. Put it in a ventilated place to dry. During this interval, the cover plate was carefully cleaned again: the place where the color was not correct was wiped vigorously with alcohol, and finally the color was basically uniform. much prettier A day later, the pre-ordered keycaps also arrived. When I installed it, I found that the layout of this keyboard is a bit weird, and some keys don't fit very well. So I temporarily found a file from the second-hand group, polished the keycap severely, and then used the ancestral vise to violently modify the satellite shaft seat, and finally the installation was completed. Plug in the computer and turn it on, and go through the button test. After twists and turns, the refurbishment is finally announced. Two packs of 55 garbage picked up Could a front-to-back comparison be a keyboard? The basic situation of the current keyboard is that part of the shaft body has not completely removed the moisture, which has caused the gold fingers in the shaft to oxidize, and the power on and off signals are not very good. This will require me to disassemble the shaft body to derust and polish the metal sheet. The current temporary solution is to drop some weak electrolyte into the shaft to help the connection. Other lamp beads, combination keys, etc. are very good, and the green switch of the miscellaneous brand is very popular among roommates. Compared with the same model sold on Xianyu, mine has the advantage of custom keycaps while maintaining a low price and normal functions, which is very superior. Keyboard basic information: HP GK100, cable, green switch, monochromatic light. The original price on Taobao is about 100 yuan. The total cost of this operation is 43.5 yuan.
