The heater works perfectly in my 3-litre tank. It keeps the water warm consistently and the red light shows when it’s active. Easy to install with the suction cup. No issues so far.

I’ve used it for a month now and the water temperature stays steady. The polymer body feels more solid than glass heaters I tried before. Suction cup holds well on the glass.
