The heater arrived very quickly. My fish tank had been at about 68 degrees for a few days. When I received the Penn Plax heater, I put it in my fish tank right away. Within 12 hours, the tank's temperature was up to 75 degrees. Although the temperature can be manually adjusted, I did not try to adjust it. I let the heater go to the temperature that it was preset to. I like that it does have the option to change your heater temperature, if you need to do so. My old heater didn't have that option. This heater works great. I'm very happy with my purchase.

This heater does its job. Red light comes on when water gets cool. The temp in the tank is dead on.
