Title: Completely useless product
Review: I bought this hoping it would warn us of a power failure on the circuit to our chest freezer. The light is cute, but the so-called alarm buzzer of 85 dB is a joke. it may be 85 dB if you place it right next to your ear, but from a distance of 20 feet, it is barely audible. to make matters worse, our unit broke in less than 3 weeks. I would not recommend this to anyone; I wish the star ratings allowed an entry of zero stars
