My old controller had preset temperatures and so it kept turning on and off every few minutes. Now I can control what the temperature range should be and, as soon as I get rid of the Hopper (runs very hot) I shouldn't have any problems anymore. Easy to program even without the instructions (which I probably filed somewhere).

I found the display fairly easy to program and it works great at the start and stop temperatures for my entertainment counsel.

have been dealing with cooler guys for almost 15 yrs very reliable and dependable products most of which i have is original and still working
