Title: Does not work very well - Poor Range!
Review: These have worse range that the ones they were to replace. These use the button cell battery instead of the 12v battery version. The range is so poor that even at the end of the driveway the garage door fails to open or close. Not until the car is practically touching the garage door do these open the door.
