Product review (2 stars): Failed at 10 months
Purchased on May 9, 2011 died on on February 29, 2012.  Coil broke, I checked the heater box and there were no signs of lint build-up or intense heat from a flash fire so it all points to coil failure.  I would have expected the coil to last a few years.

Updated 3/7/2012:  Ordered 2 of these on 3/3 to replace the one that failed on 2/29. It arrived today, very quick shipping.  I will see how long this one last.
