Highly accurate due to the use of precise micro-switch technology. Free positioning in the aquarium, suction cups provided. Can set the heater vertically or horizontally. The unit is completely submergible. Self limiting: the patented PTC heating system guarantees operations in complete safety because in case of dry running there is no danger for damage.

Rating
The unit consistently delivers the same temperature, which is good, but that temperature is always about five degrees higher that where I set it. So if I want my tank at 77 I need to set this to 72. These products are all about accuracy and consistency, and this unit has not been so great. I’m too lazy to make a warranty claim, but I figured other customers should know my experience.
