I can't say that this is one of my favorite products. We have been using a few of them at the office. One of them is a bit damaged but it still works fine. Whenever you turn one of them on (even after it has been off for a day or so), it will have a burning smell that will last for about 5-10 minutes, which is a bit unpleasant. It does heat up pretty fast though and it seems safe and easy to move around with the handle. It is able to heat up a small room very quickly and keep it very warm, not entirely a large one though. One would have to stay very close to the heater when you are in a large room to actually feel the heat. So, i would recommend this for smaller rooms or for individual use.
