It happens to all of them at some point. When you produce and sell as many bows as some of these manufacturers, its bound to happen. When a company uses a new design or component such as this, the news doesn't surprise me. Another reason why I'm giving the Guardian a couple years to see how it shakes out.

Store that much energy by man made parts and you're going to have this type of thing from time to time. Maybe that Dren was made on a Friday afternoon.
