Works better than a $20 detector and fails almost everything it touches. But still too many false positives. It sounds like a small leak has been found, but you cannot confirm this with another test or detector, or after resetting and restarting this device. Agree with another reviewer on not recognizing in light winds. I will try another model/type.
