Interesting read. Surprised no one has mentioned the shipper. I would venture to guess that more stuff gets damaged in shipping than you may think. Just because it went from the "factory" to you doesn't mean 10 other people haven't tossed it around in between. Just sent a box of lifters back to Summit a few days ago. They came out of their factory ( individual ) packaging and were all jumbled together in the bottom of the Summit box. Summit's packaging wasn't that swift, but the box looked like it had been dragged behind the UPS truck for a few thousand miles.
