    I installed a few of these around my house, including in the laundry room. Behold, my washer sprung a small leak and the system's alarm went off. If I didn't have this, it could have been much worse. Worth the money for the peace of mind.

    As is normal for Ring products, they just flat out work. It already saved us from a flood under a sink. I ended up buying 6 more!

    Very easy to set up and gives me peace of mind that I will be notified if there’s a leak in my basement. I haven’t yet had to use it but I did test it out and it alerted me as soon as it sensed water.

    Great addition to my ring system. Luckily it has not been tested yet so I hope I never have to find out if it really works. I plan on putting these in each bathroom, laundry and under the kitchen sink. Could save thousands of dollars in damage.

    Does the job of notifying you of some pretty nasty circumstances (water or low temperatures). It's a really nice option if you are a customer with a Ring alarm system. This is the kind of smart add-on that makes smart products really awesome. Before this you had to go to ADT and buy their solution.

    Seems to be working so far (no alerts yet, which is good). Placed this next to my sump pump in basement as an easy alert setup. Easily connected it to my Ring Alarm System.
