I use this floor heater all the time at my office. I work in the service department and my desk is near the doors and during the winter is can get really cold in here. I had ordered this through staples. It seems to be working really good and the quality is unbelievable. You do have to take an air duster and blow the heater out once in a while because you will get this burning smell coming from it.
The floor heater has several different settings to choose from on the top of the machine. You have how high you the heater to go and then the temperature. I really like this. If you put the machine on too higher on temperature it will burn your feet, that is how hot this machine can get, which is a good thing. I would not recommend putting your feet too close to the machine.
The heater also has a safety feature which is really good. If it was to be knocked over it automatically shuts off. Also if the heater is sitting on top of anything on the floor it also shuts off. I really like this. It makes me feel safe when leaving work when just in case I had left the heater on by accident.
