It doesn't matter if the strap was too thin. It doesn't matter if there was no strap at all. If a controller flies out of the gamer's hand, it is 100% the gamer's fault. Saying otherwise is like me playing actual baseball, swinging the bat, letting go of it and it hitting the pitcher in the head and then I say it's the fault of the company that manufactured the bat. I say BULLSHIT. You were messing around and it bit you on the ass. Learn to deal with it.
