The heater works perfectly in my 20-gallon tank. It maintains a steady temperature even during colder days. Easy to install and the temperature display is clear. My fish seem more active and healthy since I started using it.

I’ve used this heater for two months now and it’s been reliable. It keeps the water warm without overheating. A bit bulky for small tanks, but works well for my medium-sized setup.

Great value for the price. The preset function is very useful—no need to adjust it manually. My betta fish stays calm and active. No issues with power or temperature fluctuations.
