The app (iOS) is well made and feels intuitive, the heater itself is very quiet even when running at its maximum power. I have using it for 5 days now and so far I'm very happy. I almost never write reviews but this company deserves to get recognition

Ofen 2 is good product and there is a good service support. The product is well designed and well manufactured. I got a minor bug issue at the beginning with the thermostat. Support solved it very quickly with an update.
