2.0 out of 5 stars Does the job, but not that well, January 19, 2010

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.

I got this heater with a fish tank that we purchased. It was keeping our 65 gal tank about 80, but when I saw where the dial was set, I moved it to 82, and it made my tank go to 90 degrees! I was shocked when I saw the temp. I had to do some fancy footwork to get the tank down to where it should be. I will be buying a new heater. Accuracy is important. I would not recommend this heater.
