I recommend an excellent wrist rest—Roccat

The current thread re injuries reminded me. I tried a few cheap wrist rests a few years ago and they broke apart within a month. I then spent a bit more on this one, which has lasted since—that's around 3-4 years.

I don't recall if I picked it because I was so happy with a Roccat keyboard I had—still have—which has a built-in wrist rest. Whatever, this wrist rest is still as solid as the day I bought it.
