I was and am disappointed by my in-tank heaters. They can swing 3 degrees up or down from where I want a stable temp. The Hydor ETH is great. Holds a very stable temperature in my 46 gal. No unsightly heater in the tank. Unit is somewhat large. The only potential issue I see is the temperature control dial could get bumped and move position. A cover over the dial would make this unit 10 out of 10 stars instead of 9 out of 10. A minor gripe for an excellent product.
