Mribob,
Whenever products work as expected then talking about not standing behind the product or not giving good customer service is a moot point. But when things go wrong that's when you may find out things you would rather not have found out.
You stated, "... occasionally some components fail on almost all manufacturers gear." I agree. As I stated earlier, what I am reporting must be a rare failure. But when it does happen -- as your post indicates, these things do happen with all manufacturers -- one would expect at least a modicum of courtesy, sympathy and respect from the manufacturer after paying many thousands of dollars for their product. One would also expect the manufacturer to stand behind their product. Before this case I had never seen any manufacturer who, when things turned bad, refused to take any responsibility and were abusive to the customer. These are the only points I am trying to make here.
