Review on Versatile Projector Tripod Tray: Secure & Mountable Platform Holder for Projectors, SLR Cameras, Laptops, DJ Equipment, Mixers, Amplifiers, Audio/Video Devices (Tray Only) by Dave Knain

Aside from the tablet being a little warped, it does what it's supposed to and looks solid enough to use with my fancy laptop. However, the stability is terrible as it only attaches to a tripod mount. The mount acts as a fulcrum for the weight of the entire tray and laptop, and tightening my tripod screw only stabilizes it. It would be better if the mounting nut was flush with the bottom of the tray but still as strong as a single screw can make it. That being said, I'm using it on a flat, stable surface that's not prone to shock, so it should serve my purpose well if I don't need to use a keyboard or trackpad while the webcam is on. this will make the whole system shake terribly.
