Review on 39 Inch Motorized Ceiling Projector Lift - Scissor Bracket, Adjustable Hidden Lifter with Wireless Control - INTBUYING by Richard Lamptey

Can't beat the price. Well built, great for my built in attic projector application. However, the guide is less than useless. You'll have to figure out how it fits together by looking at photos of the assembled blocks online, although it's not that hard. I also wish it had a 12v trigger, but it only has a 315mhz wireless remote (and onboard controls).
