I only have two pair of Rivets so far and haven't had them for long but yeah, my initial impression was the buttons were "wobbly" for lack of a better word. But they seemed to be attached really well, I'd imagine this design was on purpose to let them have some give/stretch so they won't pop off under pressure. I dunno, it's early and I'm probably talking outta my ass here 
I thought the same think and believe it is by design. Seem solid so far












I would have thought New York to Boston would be much quicker...
