When I first connected, I couldn’t figure out how to find the device on the phone via Bluetooth, it turned out that before that I needed to switch it by holding the connection key with the second device for a couple of seconds, and after that the keyboard was displayed in the search as MX Keys (device name). Switching is fast. Some pros: Scissor keys, full size keyboard, function keys. Works with Linux Ubuntu, Debian. High quality lighting. All that is required. Cons below: For some, the weight of the device may be important - the keyboard is quite weighty, but due to the all-metal case, these are already nit-picking
