### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Pretty loud and appears to work fine.
  

*by T***J on Reviewed in the United States on December 23, 2012*

We haven't had another leak in our basement so the 2 alarms I purchased have not been tested in a real world flood yet, but they tested fine with the wet finger test and should be loud enough to be heard upstairs in our main house.

    I could see this easily doing thousands of damage to the flooring and drywall ...
  

*by K***A on Reviewed in the United States on November 10, 2014*

Saved me thousands in repairs!  Bought this thinking I'd likely never see it in action, but to my surprise about 3 months after dropping it under the hot water heater that supplies the kitchen and laundry room, my wife called me at work and said there was an alarm going off but she couldn't tell where. I paused for a second then thought of this and said to go look in the closet that houses the hot water heater in the garage. Sure enough, the top inlet pipe on the heater had a hairline crack at the connector and water was running down the side of the heater to the floor! She cut the supply off and called a plumber immediately. Had the alarm not gone off, I could see this easily doing thousands of damage to the flooring and drywall in both the garage where the heater was, but also into the kitchen that's on the other side of the wall! There was barely any water around the heater, that's how quickly it detected the leak! Highly recommend!

    Does not work
  

*by J***R on Reviewed in the United States on June 16, 2014*

This product did not work at all for me. I installed the battery and tried testing it, but the alarm did not go off. I then installed another battery and submerged it in 1/2 inch of water, and it still did not sound. I was going to return it, but it seems like I can no longer. It looks like this product has many great reviews, but unfortunately, the product I received was probably a dud.
