Review on Keychron K3 V2: Ultra-Slim 84-Key Wireless Bluetooth/USB Wired Mechanical Keyboard, White LED Backlit, Low-Profile Gateron Brown Switch - Mac Windows Compatible by Anastazja Awgustinop ᠌

This is my first mechanical keyboard, so I can only compare with a membrane and scissors. I took it for work in macOS and a little for games. Surprisingly, even on bluetooth you can play quite calmly, there is no lag. Looks extremely cool, works 5/5. It's nice to print. A bunch of backlight modes for every taste (by the way, you can turn off the backlight with Fn + 💡). There are two switches on the back: macOS / Windows and bluetooth / cable / off, they are not visible in the photo. The first switches key layouts, the second - the operating mode. The backlight has almost no effect on the operating time of the keyboard. Charged for the first time and worked with backlight - worked for 2 weeks. I charged the second one and turned off the backlight - it worked for 2 weeks. After 10 minutes of inactivity, it goes to sleep, by any pressing on the keyboard it turns on and connects to the laptop in about 1.5 seconds. I tried to connect to the phone - it works. I don't know why, but it works. You can connect up to 3 devices at the same time and switch between them using Fn + 1/2/3 The current charge can be viewed by pressing Fn + b. For white backlighting: the entire keyboard is on if the charge is above 70%, if the charge is 30-70%, the first row of keys will not light, if it is below 30%, the first two rows will not light. For RGB: >=70% - green, 30-70% - blue, <30% - red. Also, on the back side next to the charging, the LED will turn red if the charge is low. Includes keycaps for Windows
