Keychron K3 vs Logitech MX Keys Mini

The Keychron K3 and the Logitech MX Keys Mini are both low-profile wireless keyboards with multi-device pairing via Bluetooth. If you prefer compact mechanical boards, the Keychron K3 is a better choice since it's available with a variety of Gateron Mechanical and Keychron Optical switches. You can also use it in a wired mode with its cable, while the Logitech only lets you charge the battery with the cable. Also, it has RGB backlighting and some navigation keys that the Logitech lacks. On the other hand, the Logitech is a compact non-mechanical board with scissor switches. It has white backlighting and customization software to remap keys and create profiles. Also, unlike the Keychron, you can use it with a USB receiver, but you need to buy it separately.
