The Watchdog Water Alarm - Early Warning Leak Detector, Model: BWD-HWA LOT of 2

The Watchdog Water Alarm - Early Warning Leak Detector, Model: BWD-HWA LOT of 2 One needs a new battery. The other one is quite loud and happy about it, as it screeched at me when I wiped it off with a damp cloth. These work well sitting up with the sensors on the bottom, but I've never had luck with this model (in general) using the extension wires. From a smoke-free, fragrance-free home with a feline.
