The idea of the wrist rest makes perfect sense, the price is attractive. However, I had to learn that quality too sometimes with such a commodity has its price. The gel pad is split open after just two weeks completely unspectacular operation. The memory effect, which another reviewer has already mentioned, I can also confirm. He seems to remain permanently. The gel is probably just too soft. In addition, my laser mouse speaks simply not as precise as usual. And no, this is not proven in mice. Finally, I can not recommend this product.
