I have used these gel wrist rests for years and they have saved me. They take the pressure off my wrist keep my wrists cool and are pretty durable. My only complaint is getting the thing out of the hard plastic protector it came in.
The keyboard Wrist Rest that I have use for over 5 years was coming apart so I bought the Gel Keyboard Wrist rest. I am noticing that it indents easily and doesn't "bounce back". It is comfortable but I don't know how long it will last..
