Review on 🔑 Keychron K4 Wireless Mechanical Gaming Keyboard - Version 2: Gateron Blue Switch, 100 Keys, White LED Backlight, USB C Wired/Wireless, Bluetooth Computer Keyboard for Mac Windows PC Gamer by Andrew Grimes

K4 with red Gaetron mechanical switches with white LED on a plastic base Physically, I really like the keyboard. It works great when connected via a USB cable, but wirelessly it lags when typing. Sometimes without typing a key, and other times it just keeps going and going like you're stuck. FIX: I decided to try again before sending it back. So far I haven't had any Bluetooth latency issues and it's worked great. UPDATE 2: There is still some lag when using the keyboard over the wifi and in fact it causes intermittent issues with the mouse too. When I use an Apple Wireless Keyboard and the same mouse (Apple Wireless Mouse), everything works without problems. I'm using it on a MacBook Pro 16, 2.4GHz, 8-core Intel Core i9, 64GB memory.
