The heater works steadily and keeps my 10-litre betta tank warm during cooler months. It’s easy to install and the thermostat keeps the water temperature consistent. No issues so far.
Vanessa Langdon –
I’ve used it in a 50-litre tank and it maintains a stable temperature. The double sealing gives me peace of mind, especially since I have a sensitive betta fish.
Piers Hart –
Very reliable. Installed it in my 150-litre tank and it’s kept the water warm without overheating. Simple design and works well with the existing setup.
