I'm stuck in the same relationship with them: MX Master 3s/4 is my perfect productivity mouse. Problem? The rubber coating gradually disintegrates and accumulates dirt. ERGO K860 is my perfect keyboard. Problem? The plastic ABS surface of the keys wears and smooths in just a few months. The first set of AAA batteries have a far longer life!

If only they didn't cheap out on the materials and plastic quality.

Same here, seems like everyone has forgotten how to make rubber products; my 10yr thinkpad is a mix of brittle and going-gooey on different parts. I'm on my second MX Anywhere

I use 5-min epoxy and a toothpick to rebuild the nubs when they wear off. Keyboards don't last long if you have calluses

I have an ergo for two years, used eight hours most days, and apart from the space bar the keys still look good. Do you by chance have quite sweaty/greasy fingers or eat while typing? I can't see any other reason why the keys would wear that quickly.

Yeah simplest explanation might be my nails being abrasive and whatever grease is on my fingers. That's with 35h a week usage and no eating while typing. Not had this issue with other decent quality mice and keyboards though.
