This was purchased specifically for work/office use.  I put it under my desk and it warms the whole area nicely.  The only thing design-wise I don't like...and this is very minor...is that it is not easy to move after it gets hot because only one side has a handle.  But...how often do you need to move the thing once you get it set?  I never move it so that would only be a downside for someone needing to tote it around AFTER it's already heating.  I'm going to order one of these for my den before cold weather sets in.
