I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
I got into mechs and bought a bunch of them over a few years, my last one being a ducky with silent reds.
3 years ago I bought a microsoft ergo keyboard and have never looked back. So comfortable.
Now, maybe what I should have bought was an ergodox, but I’m too happy to justify spending $150+ to try it out.
