For two years, I had the "3M Large Mouse Pad with Gel Wrist Rest, Black Leatherette, Antimicrobial Product Protection", but after eight months, the thick, hard silicone pad started to curl at the edge forming a bowl. This made my mouse arrow bounce around and less accurate. The Belkin mouse pad is similar with its very comfortable wrist pad that barely feels like you are resting on it. The gel immediately fills back when you release your wrist.
