I can't speak to the issue of longevity, since my opener was installed just 3-4 weeks ago, but it functions beautifully. It's so quiet, like a babbling brook, compared to my old noisy Sears opener, which gave up after 11 years of service. The remote opens the door from several houses away, and the keypad is a wonderful feature. Now I can go for walks without having to carry a remote with me to get back into the house. (As long as I don't forget my 4-digit code!)
I opted for Sears contracted installation, which was a job well done on a very, very cold day. The only problem there was...
I bought two of these openers for my new construction house and had them both installed in 5 hours. The instructions were easy to follow and even gave you a few extra parts!
We've had the opener for over a month now and what a difference. As stated in the desription, it lives up to its word...very quiet. Previously had a chain drive which was very noisy. We have a living space above the garage and we can barely hear the opener when it is activated. Also, just to reinforce how quiet it is, our three cocker spaniels don't bark anymore when the door goes up...they don't hear it! We had it installed by Sears and the two gentleman had it up and working in 45 minutes. Very professional!
I would suggest going to Chamberlains website. chamberlain-diy.com Find the opener you like, download and review the Owners Manual before you purchase. If this is your first garage door opener, I would recommend looking a page 23 of the 1/2 hp belt drive. It refers to a vertical reinforcement plate for the topof your door, where the lifting bracket attaches. It is not part of the haedware. Your local hardware store might carry one. I installed two units a month ago and I am very please to date.
I love this Chamberlain Whisper Quiet belt drive garage door opener! You might think that "love" is a pretty strong term for a garage door opener, but after you've lived with a super noisy screw drive one that had numerous issues, including not closing all the way and going back up as you leave the driveway - and then you install this one and find that it works great and is SO quiet - well then you'd understand why I love this one! LOL
Honestly, we are very happy with the way this one operates and would definitely recommend it.
“Nice quiet opener. Used the battery back within the first month!”
