My wrist would press on my desk and hurt prior to buying this mouse pad, now the gel on the mouse pad separates and my wrist just presses on the mouse pad instead of my desk. 2 Stars because it's better than nothing but I would never suggest this mouse pad to anyone else.
UPDATE: just over a month later the gel in the mouse pad has spread to the surface where the mouse is and the whole thing is broken. 1/5 now.
