Query: Hope I can Return it

Don't buy it. Doesn't keep in sink with the outside sensor. Only 20 feet away, and through one wall.I reset it 5 times. Each time it started working and then lost communication.Judging by the reviews some work great and some don't, this one doesn't.Why take a chance. Wish I could return it. Purchased 8 months ago.
