As already described by other people, the palm rest stinks of rotten extremely damp cellar. This smell is only slightly even after months away, and initially it will interfere with adhering to the wrist rather than the smell of a then. Meanwhile, I find it less and less on, or stuffiness has indeed eased a little more than I thought.
Otherwise the product is exemplary and helps the one during gaming or the like, does not tire too quickly, or prevents the tendonitis. :)
