The doorbell was intalled and worked for half the day. Then I got a call saying the bell would no longer ring. I went up there to check it out but button # 1 would not ring, button # 2 did ring. Changed the batteries around but button # 1 still would not work. Put everything back like it was before and only Button # 2 worked for a couple hours, then it died. Not good quality, pass on this item. I can say this though, Amazon backed up this sale and I did not have one issue with the return.
