Review on Genie Battery Backup Model 6072H-B Wall Mounted Garage Door Opener, Black by Clete Dean

Installation was very easy. So was programming it. Most impressive is the low noise. The click to release the door lock is just about all I hear. The rest is noise the door makes by itself anyway. Remotes from the cars work from the end of my driveway, about 200 feet. (The door starts with a somewhat lengthy delay, wait a few seconds there she goes)The battery on my unit came in handy on day 2 already when we had a power failure. Slower, but opens and closes.There is a low humming noise audible when it’s quiet in the garage. I believe it’s the transformer charging the power failure battery.The little keychain remote is overly sensitive, I bump it with a key or drop it on the table and there goes the garage door open or close.
