Rated 4 out of 5 by Project Engineer from Decent little controller These little controllers come with a good array of features for the price. However, the mounting clips they come with are cheap, easily broken, and very difficult to get replacements without ordering a whole new controller.

Rated 5 out of 5 by Trevor H from Great Temp Controller Controller was easy to install and program. It’s operation is simple and efficient. Very good quality build. I will use this brand for process controllers moving forward.
