## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to install, worked great
*by K***H on March 28, 2024*

I like the easy install of this unit. I tested the valves before installing, opened and closed just fine. Tested after the installation, still ok. Added batteries as backup in case power goes out. Happy for now, will update review if there are issues in the future or if the unit fails.

### ⭐⭐⭐⭐⭐ Does what it says it will do…
*by O***. on February 6, 2023*

Shuts off water in about 3 seconds. Suggest 2 improvements; Better secure wires to terminations and change green Close LED to Red. Bothe Open and Close LEDs are Green. and 1 new feature; add remote access/WiFi capability.

### ⭐⭐⭐⭐ Great concept
*by W***R on March 1, 2024*

I would have liked the ease of already having hose connections. However I tested the valves before installing them they both closed but only one opened back up. I suspect it was a wire not making contact. But it was not for me to trouble shoot. I sent them back. Also the outer shipping box had all the parts loose and out of the manufactures box.
