Mary Churchill –
The heater works well in my 4-gallon tank. It stays stable with the suction cup and keeps the water warm without overheating. Easy to install and fits perfectly on the side of the tank.
Robert Alsop –
I used it for my small community tank and noticed a steady temperature. The suction cup holds well, and it doesn’t interfere with fish movement.

Great value for small tanks. It maintains a consistent temperature and is simple to set up. No issues after two months of use.
