Many YoLink users report that these sensors have already saved them thousands in potential repairs. One reviewer mentioned: "The sensor alerted me to a slow leak under my kitchen sink that I would have never noticed until it was too late. The notification came through immediately, and I was able to fix the issue before any real damage occurred."
Another homeowner shared: "I placed one near my water heater in the basement. When it started leaking at 2 AM, the loud alarm woke me up, and I was able to shut off the water main. The plumber said I probably saved $20,000 in basement repairs."
