5 Pack Water Leak Detector, Adjustable 0-100 dB Loudly Wet Moisture Floor Water Alarm Leak Sensor, Sink Overflow Pipe Drip Alter for Home/Kitchen/Basement/Bathroom (Battery Included)

Ordered the 5 pack kit. Came as advertised. Complete with batteries. 4 Stars as 4 out of the 5 worked. The 5th water sensor would not work.

Tested one and very responsive. Recommend, Great.. Brought for my RV.

These things are great! They are simple to use and function just as advertised. We had a sneaky leak under or kitchen sink. By arranging several of these on paper towels in the areas that were getting wet, we were able to find it and fix it. We then re-used them when we had a new dishwasher installed. They picked up a leak from the air gap that would otherwise have just dripped every time we ran the unit until we finally figured out there was a leak way at the back of the cabinet. Useful item. I'll be hanging onto them.

These are a great addition to keep on hand. They are SUPER loud and do their job accurately. I am grateful for the creator of these sensors as they really give great piece of mind. It does take batteries, but we've had ours for nearly 5 months and they are still going strong.

One went off behind my fridge from leaking ice maker line . Saved my kitchen floor .
