Our Verdict
Keychron K3 (Version 2)
Logitech MX Mechanical
The Keychron K3 (Version 2) and the Logitech MX Mechanical are both low-profile wireless mechanical keyboards. The key difference is that the Keychron comes in a smaller form factor by default, but the Logitech has a compact version called the Logitech MX Mechanical Mini. Also, the Keychron is fully compatible with Windows and macOS, while the Logitech is only fully compatible with Windows as a few keys don't work on macOS.
