Our Verdict
Based on our scoring, the Logitech MX Keys S Wireless Keyboard comes out on top with an overall score of 9.5/10. The Logitech MX Keys S is the benchmark for wireless productivity keyboards. The spherically-cupped keys (each key has a slight concave dish) provide tactile feedback that aids fast typing without mechanical switches. Smart backlighting activates only when hands approach the keyboard — extending battery life significantly. Logi Bolt provides a reliable 2.4GHz connection when Bluetooth is crowded. The full-size layout with numpad serves spreadsheet users well. Logitech Options+ software enables per-key customization, macros, and workflow integrations.
