Water Sensor Alarm Leak Detector - 95dB Audio Alarm for Water Detection with Leak and Drip Notification Sensor for Kitchen Bathroom Basement Laundry Room Garage (Pack of 3)

I originally got these because I only needed three and they came in a three pack. I'm very happy with the purchase as they are very sensitive, and I tested it with water. Easy to put together, and use, and they even threw in the first 9 volt battery.

I had put these under sinks and in the water heater room , wouldn't you know it the water heater crapped out and the pressure relief valve popped, in an instant the alarm went off and was able to immediately shut the main water valve off with hardley any water clean up,this definitely saved a flood. The audible alarm is loud so you'll definitely hear it. I plan on getting the water ring sensor so you can be away and get notified if water is leaking. For the price this it was well worth it ..

Works fine for detecting water or moisture. Great for under bathroom or kitchen sink but I bought them mainly for the basement by the water heater and washing machine and it’s not very loud

This is a well priced alarm system that I wish I had heard of years ago

Super easy to set up. Just pop in batteries and put one on the floor or under the cabinet to alert you of leaks! I had a leak in my basement bathroom that i wouldn't have caught if this little guy hadn't been there! Saved me thousands in remedial costs!

So thankful I bought these! Ironically, saved me from a liquid spill (not water). I keep one in my utility closet where my water heater and washer/dryer are located. I set a jug of Downy on a shelf, and it must have been placed crooked and the lid was not sure. Shortly after, the piercing sound alerted me something was amiss. Expecting to see my water heater leaking, I was shocked to see Downy all over the floor. Luckily caught it before the whole bottle spilled. Well worth the money!!!!

These alarms work a little too well. They go off if the bathroom is a little steamy.

The alarms are super sensitive and loud enough that they woke me up at 4AM with a leak under the kitchen sink. Batteries are easy to charge unlike the Govee ones I had to replace because I couldn’t open or close the tiny eyeglass type screws.
