I purchased the first unit and it lasted 9 months and they replaced it.  Then that unit lasted 7 months.  I called them up and they basically so-oh well, to bad.  Really?  You make a faulty unit that doesn't even last a year, and you tell a loyal customer-to bad?  Come on now.  Are you that big that you don't care about the product you put out.  I've learned.  Next time I'm buying a quality product from a quality manufacture.  I've learned my lesson from these guys.
