Its just been a week since I purchased the 5 fin heater. It does take some time to heat up but works well for medium or small spaces. Its good to for preheating a bedroom and I don't mind leaving it ON overnight at a 400w or 600w setting. For my large living space it only raised a couple of degrees in an hour of operation (on a 600w setting). Might have to buy an additional unit or a radiation heater for more immediate relief on chilly nights.
Looks good, energy efficient, inexpensive
less effective in large spaces

I purchased this to take the winter chill out of my babies room. The heater doesn't get very hot,which wouldn't suit a large room and at first I didn't think it was appropriate for the room I had it in, but now I think its great as it doesn't heat the room too much but just take the chill out and makes it comfortable, which is what I wanted. And I also think its safer for a childs room as the heater itself isnt too hot too touch.
Great for childrens rooms
