Guardian Leak Prevention System @ Home Depot $50 $50.02

I was in Home Depot picking up some Phillips Hue lights and on the smart home section where all the NEST and RING products are displayed they had the Leak Prevention System with 1 Leak Detector on Clearance for $50
Reviews are mixed, but for $50 maybe worth a go. My store had 3, i picked up 2.
No plumber required

Includes Valve Shutoff Controller with Battery Backup, 1 Leak Detector, 1 Sensor Probes
Closes Off Main Water Supply When Leaks, Freezing Temps or Earthquakes are Detected
Use iOS or Android App to Control System from Anywhere
