Product review (1 stars): Lasted six months
There is a very high failure rate of this unit having to do with an over-temp sensor which opens - rendering the unit inoperative. A nickel part that causes a several hundred dollar repair cost. I've had two original units fail (mine and my mothers) within a couple of years of purchase, out of warranty of course. The replacement fits right in, I hope the design/manufacturing problem has been solved.  It lasted about six months and failed the same way as the original unit.
