Too cute!  This is small, but it produces nice heat.  It did a great job warming up a 12' by 36' open attic room in just a little over an hour!
You do have to assemble the legs which was no problem, but an answered question reported that the legs were metal.  They are not; they are a sturdy plastic.
My biggest issue was that darn sticker on top.  I haven't really worked to get it off, but I did try.  It started to leave adhesive behind as reported in other reviews.  Why can't this information be printed on paper and tied to the heater?  This is why I gave it 4 rather than 5 stars.
