I am absolutely satisfied with this heater. Lightweight tool, uncomplicated setting up, easy handling. I live in a big old building, in the cool high ceilings very quickly. As I come late in the evening and my home heating in the living room on the day point to the smallest level, it is always pretty cool for a cozy evening. My heater in the evening only make up, does not pay for the short evening. After I've read the customer reviews, I thought that the heat wave heater is just right for my needs. It has already proven itself in practice totally. After I turn it on, I feel on my sofa equal toasty warm. I can not do so quickly with the conventional heating. And if it's warm enough to me, I turn it off easily and consumes no more energy. Very convenient!
