This is a nice compact heater to fit under a desk or whatever.  The fan does a better job pushing out the heat farther than the heat dishes on the market.  There are 2 setting dials.  There isnt much difference between the 1 and the 2 on the left dial.  The right dial doesnt allow you to change the amount of heat coming out, but the time interval between automatically switching on and off (or staying constantly on).
