Ask HN: What's your favorite software-free keyboard and mouse?

I've lost all patience with Logitech. I currently use their mechanical keyboard and the new version of the MX Master mouse. The hardware is good, but the software is obnoxious. It's not unusual to see 5 or 6 Logitech processes running. In my opinion that's ridiculous, so I'm looking for good replacements that require zero software.

What's your favorite (software-free) keyboard and mouse for programming?
