Pros and Cons

Control says 85 but registering 79. Poor quality control for checking accuracy.

Itc-308-wifi controller attached the the heater as a backup as well.

Colbalt aquatics 100 watt heater for my turtle tank is wonderful. Watt for a 20 gallon tank for my two aquatic turtles. The 25w cobalt works like a charm and maintains my 3 gallon at a consistent 78 f.

Sometimes the internal thermometer needs to be reset. Slide it back into the bracket easily.

The build quality is outstanding. The accuracy is on par with eheim imo. The recent models are fine, and i'll be sure to update my review if anything ever does happen.

The button to adjust temperature is hard to press. It is not tactile and is hard to tell that it was pushed. The heater suddenly gets stuck at 94 degrees and will not budge.
