The heater makes a high impression and fueled my small bathroom on level 1 very quickly. I would buy now no longer cheap, and the size is very pleasant, it just did not stand around as a Klopper. The device is not silent, for winding room may not really recommendable, but the sound is nich disturbing and I am in such matters quite challenging-it is a fan heater ergo itself as rotating a fan and generates noise-but I'd say or pleasant . which are to be tolerated. The knob is not very handy (a ribbing would be nice), that would be a point of criticism, but that's it. I am happy with the purchase. The heat output is actually perfectly adequate :-)
