Pros: sets up relatively easily, and has a nice quality wrist rest, mousing surface, and large work area.
Cons: The little plastic spacers used to accommodate different desk thicknesses are a pain to use as they don't snap together or even snuggly fit together...so they will fall out a few times when adjusting. And there is no way this fits 3/4" desks. I have a 1" desk that I was install this on, and had to use approx 1/4" of extra spacers made out of taped together business cards.
There is too much weight on this for the command strips, which is why the track has holes predrilled for screws. All the command strips do for you is hold it in place for you to screw it into the bottom of the desk. My staff kept having this fall off and be unusable until I secured it with hardware.
The front plastic piece that serves as a decorative cover for the front clamp didn't fit, and I was afraid I'd break it trying to force the tabs into place. So minor fashion sacrifice, but doesn't affect the use of the product.
Overall Review: This is a great solution if you want reduced work installing one of these units. Most keyboard trays require using templates, and putting together the track and guides. Even with having to install two screws, it was significantly easier to install than any other tray I've purchased.
Worth buying, but don't believe the hype about "tool-free", and definitely expect implementing makeshift solutions for anything less than 1" thick.
