Very nice heater combo. Keeps my 155 gallon tank and large sump warm. Right out of the box, the digital readout displayed EXACTLY the same temperature as a certified laboratory thermometer that I brought home from work to calibrate it. The controller could also be used with any heater if the Finnex one ever fails. It also does not lose its settings during power failures.
Now... the only thing I dont yet like, but maybe they all work like this... I set it for 77.5F. It will drop to around 77 or 76.9 before heating up to around 78. I kind of wish it kept it at an exact temperature instead of the up and down. This may have some kind of energy saving advantage though. I am not sure.
