Product review (2 stars): I recommend not buying this one but get a higher quality ...
The heating coil works so far but after only 5 months, the high limit thermostat failed.  Nothing was wrong, it wasn't too hot but the thermostat tripped and once that happens you have to go back in and replace it.  I have read SEVERAL reviews from this vendor about the thermostat failing so I don't think it is a fluke.  I recommend not buying this one but get a higher quality OEM set of parts.  Lesson learned here.
