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.

Brilliant product! Water heater/AC unit previously flooded my floor a few random times. Now this wonderful little device has saved me from a lot of stress. The slightest dampness will trigger the alarm. The alarm is loud enough to hear several rooms away. I have recommended this sensor to many of my neighbors. It is also very affordable.

Well worth the money these are very sensitive to water. I put these under my sinks and had some condensation from the sink drop onto the detector and it went off. It is at a good volume to hear from the basement. I would recommend to have piece of mind of water leaks in your homes.

easy to replace battery, good testing, Loud alarm

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.

This thing works! I tested it out first, then placed it in a spot that is at risk of a leak (near our old washing machine that we had fixed). About a month later, this product has alerted us one morning and saved us more than its price in floor damage. We are very happy with it.

Nice and loud!!

These alarms are wonderful! One of these saved us from having a flooded basement, when our water heater began leaking last summer. The puddle was very small when the alarm went off. We have about 10 of these units around the house, wherever there is the potential for water leaks. A simple device that does what it was designed to do. BTW, I replace the supplied batteries with Energizer Lithium batteries, which should last 10 years. Highly recommend!

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.
