I use the Patton 1500 Watt Utility Heater under my desk at work. I did not have much decision on what to purchase so I could not be very picky. In essence this space heater does the trick and keeps me warm. However, the temperature guage is not very accurate. At times, at the same setting it will be too cold, other times it will be too warm. In addition, I have to prop the heater up in order to keep my body warm. The heater in itself does not heat the space....if it sits normally, all I get are very hot feet. With the heater propped up, it should have an automatic shut off feature to prevent fires....
