I've been riding mine for two months and they're still perfect. Now since you sold two completes, I would assume they're younger riders, since more talented riders generally prefer to customize their scooter on their own. From that, you can assume that both forks could be the result of someone who mistreats their scooter.
I ride these, my good friend Dylan rides these, Ryan's riding the same ones as over a month ago as well. Although, this is the original blunt fork (SOB or whatever) and we're all riding the Blunt Declares. That may have something to do with it, although I doubt it.
