Steve, I had one very similar to that. Was trying to monitor freezer in basement and one in the garage and mounted receiver in stairwell. Kept getting false alarms because of lack of range so just put in basement. Dropped when changing batteries and cracked casing. Wouldn't work afterwards. They are loud enough to hear from garage or basement though.I've had it for about 5 years now. The range isn't strong enough to have the receiver in the house. But the alarm can be heard from the back door. I just ordered this for the freezer I have coming.
