First, all brands have failures. You may have not had a failure with 10 other brands you've used for 10 years that doesn't mean that those brands have any more or less like hood of eventually failing. The industry rate for Pro Mi gear ( essentially anything you could buy at GC) is about 1-2% over the course of the warranty period. I don't have any evidence but I'd guess that the way users treat their gear is a contributing factor here too.
If you've owner enough gear ( like hundreds of pieces) then you've probably had something dead out of a box or die in the first dozen hours. That's the way it's gonna be until,you are willing to pay NASA prices for consumer gear.
The other thing is that in my experience while working with 2 major manufacturers is that about half ( I was gonna say even higher but I thought no one would believe me except those that have worked for repair facilities) of the gear sent in can not have the problem reported duplicated in the shop. In simple terms, it ain't broke. It's probably hooked up wrong or mis-operated.
Manufacturers will bend over backwards to help you through your problem ... So be nice to that poor customer service rep when you call them
