It is quiet and I can control from a distance. I love the feature that the light stays on as long as there is motion in the garage as this enables me to get my groceries in the house without having to mess with a light. It is nice that the garage door will not close if something is blocking the beam of light on the side of the door closing mechanism.
Learning that there is no app available on Google Play AFTER I installed the GDO was bad enough, but realizing I could lose app control for an existing Craftsman GDO at my other residence when I do something like uprade to a new phone is a deal breaker. Craftsman support had no clue. They sent me to Chamberlin Assurelink, who blamed it on Craftsman and sent me back. As I am writing this, still no app. Craftsman Feedback resulted in another "escalation" number that led to Groundhog Day! It amounts to false advertisement. Existing owners, don't change phones! And Don't Buy Craftsman
Mine is not quiet. The electric motor makes a high pitch whine during operation in both directions...up/down. Does not change even with the door emergency release disconnected to insure it was as a result of being under a load. I compare it to what a dremel tool sounds like. It is audible enough to hear it inside my home. This unit will be returned and I will purchase a Genie.
Install was simple enough. Few steps in the instructions were strange but if you're handy at all you can work through them. Have not used the app at all yet. Replaced a decades old screw-drive opener where we had only one way to open it, so having two remotes, a key pad, and a pad on the wall all working is 4x better than where we were. And this unit is very quiet.
Nice and quiet operation. Good installation service.
