If you sit at the key board for hours each day, your wrists and hands probably get just a tired as mine do. I've never used a mouse pad with a wrist rest on it so it did take some getting use to but after a few days of adjusting to it, I love it now. My sister in law had to have wrist surgery after years of typing and getting carpel tunnel and I didn't want that so this was a great product to get.
This would also make for a great gift for someone who sits at the computer all day for work because you just don't realize how much you are working your wrists when typing or using the mouse. Both the wrist rest and the mouse pad with the wrist rest built into it are very light weight and seem very durable. I expect they will last a good long time.
