BLACK+DECKER Desktop Heater

I purchased this heater in February from Amazon and it worked great for the last couple of months. It provided great heat, and had a safety feature that would shut the heater off if it got tipped over. Fast forward to June. This last week after being on for about ten minutes, this acrid, burnt smell started coming from the heater. This was followed by a metallic sound coming from inside the heater, then the heat stopped. Of course, I unplugged it right away and e-mailed Black & Decker through my Amazon Order page. I heard back promptly from a person who said that another company handles this heater as one of their "licensed partners". So apparently Black & Decker doesn't handle its own merchandise, at least not in this case. The person who e-mailed me forwarded my e-mail to this third party company and I hope I hear back. I really liked his little heater, but am afraid to take a chance on it again as I'm afraid it could possibly be a fire hazard. Please be cautious and don't leave this heater unattended. Another Update: I still have not heard back from the company that is licensed by Black & Decker to sell (or make) its heaters. I can't return the heater because it is beyond the return period, so I guess I'm stuck with a heater I won't use because I feel it's unsafe to do so.
