Logitech MX Keys S
Low profile, feels like a laptop keyboard. No wrist rest, which means it can sit right at the edge of the desk and my wrists hang off into the void. Most comfortable position I have found. Undefeated champion.
Replaced
Logitech K860
Wanted to try out an ergonomic keyboard. Not my thing. Too tall, and the wave layout did nothing for me except put more strain on my wrists.
