Product review (1 stars): Piece of Junk  Made By Spark Plug Company
We purchased this product 3 years and 3 months ago (May 2010).On Sat Aug 17, 2013.
It died. Fortunately I bought extended warranty. No weekend service calls. Make sure your appliances don't break on the weekends. Service tech said it needs new relay board which he might be able to get this week.
WARNING: Do not by this piece of junk, and I you have I hope you bought the extended warranty because you are going to need it.
