🏆 “Seems to be an excellent device. It was extremely easy to set up and I tested it by poring water near one of the sensors and immediately received an email telling me of the “spill.”

One shopper said this device is “great [and] easy to set up and put in action!” They added that it provides “great peace of mind.”

Another person said, “A few accidental splashes easily triggered the sensors.” They confirmed the “alarm [is] clearly heard in house as well as [via an] app notification.”

“Life-changer!” exclaimed a third. “Our daughter who showers and somehow gets water outside the shower curtains onto the tile floor […] led me into looking into these devices,” they said.
