### ⭐⭐⭐⭐⭐ Well Made

Worked Great

### ⭐⭐⭐⭐⭐ Works as advertised.
*by J***S on July 28, 2025*

I used this to control my Sprinkler relay. It was easy to set up and works well.

### ⭐ Disconnects from WiFi every 12 hours
*by B***E on June 8, 2025*

Wifi is not stable. Disconnects every 12 hours like clockwork. I believe problem is due to error in firmware. You must interrupt power for it to reconnect and it stays connected for another 12 hours.
