Query: poor product

Do not buy this product unless you like crawling under your desk to retrieve the screws. This is a flimsy plastic tray. The 1/8 inch screws keep falling out. The tray drops and the screw flies under the desk. Spend money and get a better product. I have the3M Knob-Adjust Keyboard Tray with Standard Platform, 17 Inch Track (AKT60LE)at home and love it. Spend the extra money. You'll make it up in lost time.
