I use this heater in my office when I get cold because of over air conditioning or not enough heat during winter. It's a great heater!!! It's fairly quiet, but powerful at the same time. You can set it to maintain the temperature at a certain degree level, or you can just have it going indefinitely. The thing I love most about it is that if you lift or move the base, it automatically shuts off. Therefore, if it's on and you happen not to be around and something happens that causes it to fall, there won't be any accidents since it will turn off by itself. It doesn't need a lot of time to warm up and keeps going without getting weaker. Good product.
