This heater maintains a stable temperature in my 300L freshwater tank. The glass is durable and the unit stays submerged without issues. Works well over several weeks with no overheating or fluctuations.

I installed it in a marine tank with mixed species. It keeps the water temperature consistent, especially during cooler nights. The design is compact and fits well in the tank setup.

The temperature control is very accurate. I set it to 26°C and it stayed steady. No need to adjust frequently. Easy to install and has been reliable for over three months.
