Yours doesnt? Mine rips hairs off my arm like a F$&king waxing kit.And not to mention how the bracelet on the MM doesn't pinch the hair on your wrist...really cool how they designed a way around that. And I don't see the band flexing anytime soon. Ever. I doubt the washers will even ever have to be replaced. Maybe....but if so, that will be way down the line. Hmmm....might be a good idea to see if you can purchase some of the washers in case they ever dry out and/or brake. Now....before Oakley is done all together with watches. Maybe Linegear can make aftermarket ones...eh...
