Review on 🐠 HITOP Adjustable Submersible Aquarium Heater for 10-35 Gallon Tanks - 50W, 100W, 120W by Sara White

Just wish it was a little shorter so I don't have to mount it on the back of the tank. Otherwise, for the price, it can't be beat. I sent back $25+ which almost boiled my tank when it was set to 80! This one stays accurate to within 1 degree and I love the low cost. I bought a second one for another tank and will definitely buy more if the need arises. I can't work with "set x degrees above room temperature" because the weather where I live is too unpredictable and the temperature in the tanks fluctuates too much. Very satisfied!
