Bests & Worsts Reviews from Amazon

I bought this unit for my office, and for about a month it worked quite well. Then, just today (1/20/11)this unit stopped working. The unit ran out of water and the automatic shut off powered the unit down. I refilled the tank and placed it back on the unit. The power light came on and I could hear a very faint whir (as normal), but no mist came out. I made sure the unit was turned to "max" and still no mist. I decided to let it run this way for a little while in case it needed to "draw" the water up from the tank before the mist was visible. I ran it that way for about 30 minutes. During that time, I left my office and returned to find an odor of burning plastic. I touched the unit and it was VERY hot--so much so that the water in the tank felt like hot bathwater (I started out with cold water). I immediately unplugged the unit and requested a refund. Had this been left unattended I hate to think of what could have happened. This is a shame, because other than this MAJOR issue, the unit worked as advertised. Buyer beware--not worth the risk in my opinion.
