Purchased this heater last week and found out that it really heats up a room. I really like the fact that it is on wheels and my 15 year-old but it together in a matter of seconds. The second thing that I like about this heater is that it is super quiet. I have never had a quiet portable heater and you don't even know that this heater is on unless you look at the light. I will have to go out and purchase at least 2 more just like this one. I don't know why I had waited this long to buy this item. You can't tip it over because it is on wheels and there is a safety button just in case it gets hot. This was a very inexpensive purchase for a room heater.
