Ordered this and is perfect for under the desk to keep warm in the office. With the safety features I do not worry about it being to hot or any open heating elements to burn me. I can also see this as being used in the water compartment of a RV in sub freezing temperatures to keep the water lines from freezing. The compact size and the 600W heating rating make it ideal for this application.
Really like the safety-button feature that stops it from running if tipped over.
