Query: Failed after 9 months! No replacements available.

This unit failed after 9 months and while the manufacturer recognizes that it is in waranty and needs to be replaced, they have no replacement stock since they bring these units in from an overseas manufacturer on a seasonal basis. To make matters worse, their internal computer system doesn't allow them to automatically ship a replacement to a customer. The customer is reponsible for constantly checking their website to see if they have any in stock. If you happen to miss that window of them getting in stock and selling out, you have to wait and keep checking.
