Bests & Worsts Reviews from Amazon

First of all, I agree with prior reviewers that this unit is very noisy vs. other forced air space heaters. The primary reason for my negative review, though, is that I think this unit is downright dangerous. I used this unit on the "low" setting for about 12 mos (used only in winter months). It worked fine. Today, for the first time, I used it on the high setting. It had been on for about one hour, when one of the internal supports for the heating coils collapsed. This caused the coils to collapse into the metal fan, which then caused a short. A huge flame shot out of the front of the unit and turned the plastic housing black. If I hadn't been sitting there to unplug it immediately who knows what might have happened. This unit has basically never been moved, so the weakness in the support is not due to operator misuse. It is likely a manufacturing and/or design issue. Very poor design. It's cheap for a reason. Don't risk your safety for a few bucks.
