Title: REALLY quiet
Review: I replaced two very old openers.My installation was complicated because my garage has a beam across both bays.The openers I replaced were several inchs shorter than the Chamberlains.The Chamberlains were too long to fit between the front wall and the beam.I ended up opening the ceiling and extending the header beam (above the door) to give more room.Once I figured that out the rest of the installation was easy.They are so quiet i realized how much noise the doors themselves were making.I had those professionally serviced and now you can't hear either door opening, even in the room above the garage.
Is the review positive or negative?
