Works perfectly fine, temperature is stable; easy to attach to the filter hose. A must have if you want to avoid seeing a heater inside the aquarium.

Keeps really stable temperature. Just finding difficult to clean as in and out flow opening smaller than inside. Nice not to see a heater in the tank
