In another review I noticed that the device is not weatherproof. The part you place by the driveway is weather resistant. The alarm (the part that goes into your house) doesn't work. Install it about 60 feet from your driveway and it will work. Better value than purchasing the same unit from Harbor Freight. Requires 1 9V battery and 3 C batteries.
