Rating : - great lightweight, portable heater I bought this heater last winter for use in a medium-sized bedroom. The room heated up very well although would cool quite quickly once the heater was turned off. It has a couple of great features:
1. You can set the heater to switch itself on and off so that the room neither gets too cold, nor to hot. (I use this feature at night so that I don't wake up sweltering - it probably saves electricity too). Auto freeze setting is supposed to switch heater on at 44 degrees but I find it switches it on at around 60 degrees.
2. It has a safety device which I discovered by accident - on two occasions a piece of clothing fell on the heater and covered it. The heater cut the heat off to prevent the unit from becoming over-heated and potentially dangerous.
We just moved to a much bigger apartment so I'm buying 2 more of these, despite the fact that this great heater is very lightweight and easy to carry from room to room.
I'd also recommeend this product to be used under a desk at work.
