I've had a keyboard wrist rest for over seven years which has done the job well. It's tired and worn, so I thought I'd buy a new one. I have a mechanical Filco keyboard so this should make it clear how serious I take my computer use and typing. The Fellowes wrist rest is about half the height and half the width of my existing rest. It doesn't even come close to being a replacement. Against my keyboard, it's so low down that I might as well just take it away and rest my wrists on the tabletop. I've opened it, so I can't return it - what a waste of money. Buyers beware - find something that does the job because this one doesn't.
