I was very happy with the comfort it provided and the low price tag. I used this wrist rest about 2-4 hours per day, but I take good care of my belongings. By the 3rd month, there I was a 1-inch slit in the cover at the base of the unit. The gel filling couldn't be contained and was spilling out. It has a very distinct chemical smell, so for fear of toxicity, I had to throw this out. It's too bad because it did work really well until it tore.
