Works great. Fast shipping and great customer service. Will buy from them again.

Works, easy to install, would buy another someday but probably won't have to in a long time

This was a replacement for one that went back. Easy installation and works great. Had to also order the replacement cord as the original cord also went bad.

I've just built a new greenhouse that's very heavy duty compared to my previous greenhouse and I just ordered this again to replace my old controller to start over as I already had the fan kit I ordered from ACF several years ago. This thermostat works perfectly and is very accurate.
