I installed the heater in my 3-litre tank and it has been working perfectly. The red light shows when it’s on, which is helpful. The polymer body feels sturdy and doesn’t break easily. No need to adjust anything — just place it with the suction cup and it’s ready to go.

The heater maintains a stable temperature in my small betta tank. It’s simple to set up and the red light helps me know it’s functioning. I appreciate that it’s made of polymer instead of glass, which makes it safer and more durable.

Great product for a small aquarium. It keeps the water warm consistently and the suction cup holds well. My betta seems more active and healthy since I added the heater. No issues with leaks or overheating.
