Well, the heater operates effectively and warms the room. That said, it's pretty loud--and there's no "low" setting for the fan--you can only change the heat level. The temperature settings are arbitrary (59, 77, 86, 95) and in any case don't reflect the actual room temp. At 77, the heat turns off quite soon, while the room is still cold and the fan continues to blow cool air; later the heat returns. You could pick a higher temperature and it would stay on longer.
