Your review: We just began using this ergonomic keyboard lift tray a week ago. So far it seems great. There were not many products that I was able to find that would fit our needs so the fact that I even found it is great.
Pros: Highly adjustable, with no a huge footprint.
Cons: Only con I can see so far is that the mouse attachment doesn't seem as adjustable as the keyboard lift itself. Also, there's no grip for the keyboard or surface for the mouse that prohibits it from sliding.
