★☆☆☆☆
Malfunctioned within a month. Waste of $.
I chose this one because the reviews were good. It malfunctioned within a month. The back of the alarm has a key for the chirps and of course mine was a lemon. It looks like it was just made August 9th, 2017. I received it at the end of October and it died mid-November. It was a waste of money.
