Water Leak Detector Sensor Alarm: Home Water Flooding Monitor Smart Sink Overflow Monitoring Adjustable Wet Moisture Alert Pipe Leakage Drip Detection Warning for Basement Floor (2 Sensor)

Works exactly how it's described. Comes with batteries and clear instructions to easy to set up. I purposefully chose this one to not have to have yet another wifi connected device. I tested on a damp paper towel and it went off. Very loud. I would use this somewhere you go by often enough vs in a storage closet in the basement with all the doors closed. Then you might not hear it. Nice and small for good peace of mind.

This thing alerts to small amounts of water, has a loud siren, and a button for silencing the siren. It has four little metal feet that I assume are the sensor array. It's a nice little device.

I set this alarm up next to my water heater a little over one year ago. I forgot about it. Last night, after spending a week on a camping trip, I heart an unusual intermittent "alarm" noise. I thought it may be the TV. No. A phone alert? No. Turns out my 6+ year-old electric water heater started leaking, which set off this alarm. I live on a slab, which means a leak flows across the first floor. It is important to catch the leak early to prevent water ruing the flooring and leaking into my neighbor's home. I live in a townhome. Having replaced the water heater every 5-6 years, this was right on time. The alarm saved me from a huge mess. I hate leaking water heaters, especially since mine is stuck in a closet, under a stair landing. It makes it hard to take an occasional glance to check on the heater. This inexpensive alarm worked!

Great little alarm. Works well. Simple to set up and use. Very loud.

Works great! I have a closet with my AC unit and water heater on top of each other and was told to get one of these after a neighbor had an issue with a leak they didn’t notice and had to spend thousands on repairs due to the water damage caused to the downstairs neighbor. Wouldn’t you know it! A few months later my AC drainage pipe gets clogged and the AC water starts to drip down into the water heater. I have one of those plastic rims under the water heater so most of the water accumulated in there and made the alarm go off. It was sooo loud. It was in the middle of the night and I was in my bedroom on the other side of the apartment with the door closed and I could still hear it! Best purchase ever!

Put in the batteries and put this to use right away. I tested it and it works fine. Plenty loud! I put one on the floor between my sump pit and my water heater. My washing machine drains into the sump pit so if anything stops working we will get an alarm and be able to turn off water before things get too crazy!

This item really works and can save you a lot of money and aggravation from water damage

The alarm is very loud hopefully if water my floor. It works well. Very easy to set up.

I tested it, it does sound when water touches its sensors. Very loud alarm for my apartment, but not sure if it is loud enough if you place it in an American-style house basement. It has consistently works for my leak. Loud alarm every time, good product.

It's just what I needed for my basement it works...what more can I say!

Fait très bien le travail mais n’est pas connecté au wifi ou à quoi que ce soit donc il faut être sur place pour entendre sonner. La sonnerie est très forte c’est un avantage

No floods yet. seems quite simple.

I held off on reviewing this as I hadn’t had a water leak yet. Our washer has leaked twice in the past year which was what prompted me to purchase this alarm. Yesterday the alarm sounded when I had a load of laundry in, and sure enough it was leaking water. I was very happy to be able to address the problem quickly without my basement flooding or the water causing any damage.
