Our Verdict
Logitech MX Keys
Logitech K845
The Logitech MX Keys is better for office use than the Logitech K845. The MX Keys' scissor switches on our unit are much quieter than the Cherry MX Blues on our K845 unit, so it shouldn't be loud in an open office. Also, it's wireless and has a multi-device pairing feature, has a lower profile, and it's fully compatible with both macOS and Windows. However, the K845 has a higher pre-travel distance, which should help prevent typos.
