About a week ago I purchased a Satechi Slim X1 Bluetooth Backlit Keyboard for my home office. You can connect unto three Bluetooth devices to the X1 keyboard. Press and hold the fn key with one of the Bluetooth keys to program. I set the Bluetooth connections to match my Logitech MX Anywhere 2 mouse. Switching between the three connections is quick by pressing the fn key with the corresponding Bluetooth key. You can also connect the USB-C cable to the keyboard and computer and press fn Eject to switch to a wired connection.
You can adjust the back light of the keyboard by pressing the F5 to turn down the brightness and F6 will increase the brightness. The back light is nice, but I only used it twice, once when I pressed the keys and then for the pictures for this post. The light does bleed out from the keys.
One key that I was missing is the Mission Control on Apple Magic Keyboard (F4). The F4 key is now mapped to a task switcher. I checked the settings and found pressing ctrl and the up arrow ^↑ will activate Mission Control.
Satechi states it will take about 2 – 3 hours to charge the keyboard. Depending on the brightness of the back light keys, you can get anywhere from 8 hours to 125 hours and 13 days of standby time.
This is my favorite keyboard. I have it programmed to connect to my Lenovo T480 work computer, my MacBook Pro, and my 2020 iPad Air. It is comfortable for my ergonomic needs, responsive keys and switching between devices, and looks great. Plus the color is very close to the Space grey on my MacBook Pro.
