Excellent heater08/04/2012 ByKristina I bought this here about 9 months ago & it's doing a great job regulating the temp in my 5 gallon tall tank. A few minor adjustments when I got it & it maintains 77 degrees with no problems at all. I have no qualms about buying more for other tanks.

Good Heater06/13/2012 ByVictor Ramos The only down side to this heater is that I have to use it at it's maximum setting to heat a 5 gal tank to a suitable temperature.
