Great quality item, easy to connect with the tuya app

### ⭐⭐⭐⭐ Plastic housing is garbage
*by M***N on November 3, 2025*

Works great! The plastic housing isn't sized correctly at all. It's actually garbage. Luckily, I don't care how it looks after I mangle it up in order to get a power cable plugged into it. But it does exactly what I need it to! The inching feature is perfect!
