These water leak detectors are very easy to set up and test. If they detect water, a very loud beep will sound. I haven’t had a water leak yet, but these will prevent a lot of water damage because you will know immediately if there are any drops of water where they are placed. Read more

All the sensors I received work and were easy to setup. Good value for the price. However, the cover removal tool only worked about 50% of the time and warped the plastic around the little removal notch. Before closing I'd suggest inserting a little piece of twine that you can pull on to lift the cover. Or don't close the cover too tightly so it's easy to open in the future. The sensors will also need a regular check for battery life since there's a low battery light and no sound. Read more

The device works. 5 devices allows distribution to two locations. The sensors pick up detection from ground level to detect spreading water, and from above for detecting falling water. Read more

Setting these up was a breeze. I just placed them near potential leak sources like under sinks and around the water heater. No tools required. Very functional little gadgets. The 100dB alarm is loud. During testing, it was definitely enough to hear from another room, which is exactly what I was looking for. If a leak happens while I'm asleep or not near the area, I know I’ll still hear it. These sensors are small and don’t take up much space, making them easy to tuck into tight corners without being in the way. I've placed them in different spots—kitchen, bathroom, laundry room, and basement—and they perform well on all types of surfaces, from tile to concrete. It’s also good to know they can detect small drips, not just major floods. Batteries are also included which is great. Overall, for the price, these water leak detectors are a solid investment for anyone wanting an affordable, no-frills solution for water leaks. They provide a loud, reliable alert, and they’re easy to use. Read more

This is simple yet easy to use water leak detectors. It's small in size but with very loud alarm. I love that these use 2 AAA batteries rather than 9V battery like my old water leak detector, which was very difficult to install the battery. 2 AAA batteries are much easier to install and also readily available at home compared to 9V batteries. BTW, I was very glad to see that brand new batteries were also included with these detectors. These have 4 water sensors on the bottom and 1 sensor on top. I also love that it has large TEST button to test the unit and it can be used to turn off the alarm in the event when it goes off due to water detection. The best way to use these detectors is to place them on top of a paper towel so that if there's any water leak near by then it will get absorbed by the paper towel then immediately touch one of four sensors on the bottom to sound the alarm. I have placed these under the sinks and behind the toilet tanks so I will know immediately if there's any sort of water leak, which isn't something that I check often. Always test it before using it to confirm that it's working and I also appreciate that it has low battery alert so I don't have to second guess and check the batteries every few months. Highly recommend these water leak detectors. It will pay for itself by just alerting you with water leak once. Better safe than sorry... 5 out of 5 stars! Read more
