I purchased this heater for the winter and so far I have been VERY impressed. I was a little worried with it being so small, but it puts out a lot of heat and it does a great job of keeping me warm. It is lightweight and is easy to carry around from room to room. It also has 10 different temperature settings and 3 fan settings (regular fan, low, and high, basically). I would recommend this heater for an office or bathroom, or smaller bedroom. It does a great job keeping me warm when I'm fairly close to it, but wouldn't use it to heat up a living room. Performance It's a space heater, it provides heat and keeps me warm. No complaints on it's performance. Ease of Use Very easy to use, twist a knob and it comes on. Durability So far it seems pretty durable; I haven't dropped it or anything, so I haven't done much to test its durability. Design Very small and compact, which I like! I can place it almost anywhere and has a handle on the back to use to carry it. Safety Has a metal cover on the front to protect anything from getting to the direct heat source, but the metal can get hot.
