I've only been using this for about 5 minutes but to be honest it's a lot better than the old Gimars gel foam I used before. It was too thick in the front and back and too soft. It is stable under the palm/wrist and fits my keyboard perfectly. Already feels much more comfortable and takes up less desk space. It's a bit long for me, but I'm using 70% of the keyboard so I can't deduct points for that. If you have a standard-length keyboard, you will hardly find it long enough.
