Title: door opener
Review: I've owned this product for almost two years now, and its performed well. My application was unique, having very little space between the ceiling and door (5"). Also the door spring sits over top of the door where you are supposed to mount the rail. I had to modify a bracket and mount the rail and motor very close to the ceiling. I should also mention that my door is fairly heavy 8X16 steel insulated.The only problem I had was the chain would "jump" over top of the piece that slides on the rail causing it to grind and bind up. This may have been due to my specific application, but it looks more like a design problem with the rubber piece on the slide. I added a piece of metal to the slide that prevents this and have had no troubles since.I've heard noisier openers, but I would not label this one as "quiet" either.
Is the review positive or negative?
