The heater maintains a steady temperature in my 55-gallon marine tank. The dial is easy to use and the glass body feels sturdy. My fish have not shown any signs of stress since I installed it.
Jonathan May –
Works well in my freshwater tank. The temperature control is responsive and the on/off light helps me monitor it at a glance. A bit bulky for small tanks, but perfect for mine.
