Super quiet upgrade
Great upgrade for a failing 23 year old craftsman opener. Super quiet and for the older opener mounting points. WiFi function is a bonus.

Very quiet
Very quiet operation; it replaced an older craftsman GDO, that was still noisily working. We are very satisfied with the new GDO and it’s remote functionality.

Works just fine.
Does the job. So happy to have the garage door working again. If you need additional remotes, order carefully.

Shop around
I chose this door opener because I have always liked the name and what it stood for and was a good quality and reliable product however nothing stays the same obviously as discovered when I purchased this same door opener from Lowe’s simply because I could get it the same day. When I opened it and tested it we discovered that it had no power (plug it in and not’n happened). So I placed an order through Amazon, received it and installed it however I noticed that the wall mount control is really cheap (no clock or temperature) and there is no sensor for the door opener lights meaning that when you walk into your garage from your house the lights don’t come on like the old unit. The 3/4 hp motor is quite yet it’s not built like a real Craftsman was. JS

Can't Get It to Work-No Customer Service
My husband has over 6 hours installing and reinstalling and still no luck getting remote to work. He has installed numerous garage door opener and never had a problem. Trying to get help from craftsman has so far been impossible.

Craftsman 3/4 HP Garage Opener
This is by far the quietest garage opener I have ever used. The installation process was simplified by an App called BILT. This app made the installation a breeze. I would recommend this garage opener, is a 5 star buy for me.
