I had been doing alot of research on space heaters before purchasing this one. I went off of the previous good reviews, and was not dissapointed. We use this for our bedroom. It heats the room up in no time and keeps it warm. Actually, if we put it on the highest setting, we have to turn it off in less than an hour, the room gets so warm. A real value for the money and I am totally happy with my purchase. And I love the low shipping fee with Overstock! It is great!
