I started having periods of numbness in my right wrist as a result of computer use. It was easy to figure out that the wooden wrist support on my desk was digging into my wrist and probably reducing blood flow and pinching the nerves in that area. After receiving my Belkin Gel Mouse Pad, the numbness is completely gone and never comes back. It is a pleasure to use and is very comfortable. I should have gotten one a long time ago. The only reason that it didn't get a five star rating was that I thought the gel cushion could have been slightly more firm.
