Title: Not worth the effort to install
Review: I bought mine at staples but yikes is this bad. The tray is cheap and wobbly from the start. Within 3 months it was coming off it's rail. The keyboard cannot retract without sliding the mouse tray in so you need to find somewhere to put the mouse if you want to slide it in (which is the whole point of a retractable keyboard tray). It has no redeeming qualities.
