I bought this leak starter kit after dealing with a small leak under the sink that turned into a big cleanup job with a new cabinet...lol. I wanted something simple and reliable this time, and so far this system has been exactly that. Setup was super easy. I plugged the hub into my router, opened the app, and it basically did the rest. Each sensor paired with one button press. I had everything installed in maybe 10–15 minutes for entire house. What I like most is that these don’t depend on Wi-Fi. I’ve got one sensor tucked behind a toilet, another under the kitchen sink, and even one in a spot where my Wi-Fi normally dies... and every sensor still connects with no issues. I tested all four sensors with a damp paper towel, and they alerted instantly. I get notifications on my phone and email, which is great for when I’m not home. A big plus for me is the battery life. These use simple AAA batteries, but they’re supposed to last years, not months. And the app actually shows the battery level for each sensor, so you’re not guessing. It’s nice to know you won’t get blindsided by a dead sensor right when you need it. The sensors feel solid and the app is straightforward. Honestly, this setup has already given me more peace of mind than anything else I’ve tried.

Notifications are excellent and very accurate when detecting water

1. The product description states "effortless installation" - placing the units is easy - but configuring the software installation is not. If you are at all phased by IT connectivity - try another system that is more easily installed. 2. This was delivered to the UK from the USA - so it came with a USA 2 pin plug.

This is a really good, easy to use system that work terrific. I have them in my home and cabin, both for water leak detection and they have saved me twice from a water leak doing major damage. Besides the leak detection I have a water temperature monitor on my hot tub and a water depth finder at my cabins fresh water tank. I have never had any issues till recently the hub stopped working and was replaced on warranty. Thanks again.
