Title: Piece of Junk from China
Review: Chamberlain should be ashamed to place their name on this thing. The price should be lowered and sold at the dollar store with all the other Chinese junk. In eleven months, it simply stopped working one day. Flashed red and green simultaneously meaning it cannot receive a signal from the garage door module. I tested the 2032 battery and it is strong. It could not even find it a foot away. Buy another brand.
