Had to return this item to get my money back. Upon getting it out of the package I notices a strong chemical smell that gave me an immediate headache; apparently from the off-gassing due to the materials used. I also noticed that this wrist pad clung strongly to my desk and did not move easily if I tried to move my keyboard around; you actually have to peel it off the desk and re-position it if you want to move it. But the toxic smell was too much; couldn't use it at all. I tried to set it aside in some fresh air for a few days in hopes that the smell would go away but no such luck. I then put it in the trunk of my car to return it to Staples. It remained there for a few days before I could get to the store and I found that I could still smell it even in the cabin of my car!
The skinnier Apple makes its keyboards the more strain it puts on my wrist. This wrist rest is ideal as a solution. The gel is cool and comfortable while the underside prevents it from sliding around during use. I have one at home and one at the office. Less strain more productivity. Recommended for those who have encountered the same problems.
