Sadly disappointed in this item. The locking lever does not hold the tray in place and I have to let the tray rest on my left leg to keep it from rattling with each keystroke. At first I thought maybe I didn't have the tray screwed on tight enough, but after double checking, everything I put together was good and tight. The mechanism that slides in and out and lets the tray tip is very loose. In this case the old adage holds true...you get what you pay for.
