I'm the proud new owner of a QFR (with reds). It's the first mechanical I've ever used and it's awesome, but my wrists have been killing me.
The rubber-dome keyboards I'm used to are so much lower to the desk. I think I need a wrist rest. I've tried a few makeshift solutions: a piece of wood, some foamcore, and a rolled up towel. Nothing seems quite right yet.
What do other people use? Does anyone use a mech without a wrist rest?
If it's relevant, I don't use the back feet. I'm actually thinking about giving it a slight negative-tilt.
