I work for a construction company and we are always working on new developments.  I work on the construction site, so space heaters are needed on a daily basis.  We have them everywhere, at least 20 on site, and the staff loves them.  They are portable, easy to use, have various settings to adjust to the different "climates" throughout the construction.  If someone accidently knocks it over, the auto cutoff feature is activated.  I would purchase this product for my home and would recommend it to my family and friends.
