## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great product design with super support
  

*by T***E on Reviewed in the United States on January 21, 2022*

I have had the base Guardian system for over four years. It is now expanded to over 15 sensors. Twice it has almost instantaneously shut off the house water when there was a leak. Once was at 2 am and saved considerable damage. The product is well designed and thought out. The first year there were some teething problems with the software however the present version is wonderful. They have been very responsive to all questions. Of the IoT devices I use (quite a few) these folks are the best to deal with and most helpful.

### ⭐⭐⭐⭐⭐ 







  
  
    It detects leaks fast!
  

*by H***R on Reviewed in the United States on June 22, 2022*

I have 12 sensors plus 6 remote sensors.  I really like the system.  Manufacture finally got firmware to work pretty well.  Still a few bugs.  It does work.

### ⭐ 







  
  
    Great concept poor execution
  

*by M***C on Reviewed in the United States on January 19, 2020*

I returned the entire system, it has WiFi issues  and didn’t work half the time. Tested system several times at random and it did not close ball valve. Not reliable enough 4 me!
