I installed this heater in my 5-gallon tank and it has kept the water temperature stable. It turned on automatically and shut off when it reached 77°F. Very reliable and easy to set up.
Maria Gibson –
Works well for my small aquarium. The temperature stays consistent and the heater doesn’t overheat. Only downside is it’s a bit small for larger tanks.
