    I use it to detect possible water leakage from AC/water heater in the attic. The battery life is good in general. I have bought 6 of them and 1 drains battery really fast (~2 weeks). Besides the defective device, I like the product.

    We purchased one of these for under our kitchen sink and one for the laundry room. Easy setup, didn't even know it was working until the kitchen went off one night. We had a leaking garbage disposal! So glad we had spent the money on these, little money for great piece of mind!
