WOW!Took a gamble on this that came with all the options that normally come at a much, much higher price tag if I'd opted for an 'established' maker.Tested it all out before I even started to make sure the motors worked. The fitted all the bracket, the rail & hoisted it up there! 1st one was done in under 3 hours incl. wiring. 2nd was up in just over an hour.Worthy of note is that one must make sure the door springs lift the door on their own else juddering can occur on closing. Had to retention torsion springs on both my doors as they had never even been set up. Dead easy to do. Also explains why it had always been such an effort opening them manually before. sheeeesh!For those thinking belt is quieter & better than chain driven you should think again. Not noisy at all & much less likely to break/stretch over time. See the video.I highly recommend these!Grab a real bargain!
