Review on Zircon Leak Alert Electronic Batteries by David Maxwell

Arrived in 24 hours and just what I needed. Unfortunately I bought them AFTER my dishwasher leaked through the subfloor, fell underground and ruined the Pergo floors. Interruption: As I sat down to write this, the alarm went off behind my fridge. Moved the fridge to find the dripping water. Either way, these things are LOUD. You don't sleep through an alarm clock when you have a small house like mine. My water heater is in my basement under my bedroom so I know I can easily hear it in the basement. They are also very sensitive. I tested them on a fairly warm day and my hands were a bit sweaty - that alone seemed to do the trick. I hope these guys prevent future water disasters!
