These things are not well made. The main problem is the "hump" that the wrist lies on is not well attached to the base. As a result the "hump" becomes disconnected from the base. Mine fell apart within about 8 months (albeit I used it very intensely [i.e., just about every day for a few hours a day]). The problem is that it is poorly glued on. Belkin should have, at the very least, used a better glue. Ideally it should have been stitched or stapled on. That way it would not fall off.
