A great unit for the price. After 1 year and 2 months, however, the backlight on the keypad is on the fritz. The backlight is flickering on and off continuously which will surely drain the battery quickly. The unit still works though. I'll update my review with how Chamberlain will deal with the issue (I can't find anywhere what the warranty period is but it will probably be 1 year!Edit: I called Chamberlain directly and they were very nice and offered to send me a free replacement unit even though I was just 2 months outside of the 1 year warranty period. I've upped my rating from 3 to 4 stars based on their customer service.
