MITCHELLST LO D'OURVILLE, FranceVerified Buyer2 of 5I'm a little disappointed with the "SURE-GRIP" nuts. They're misnamed. After half an hour of skating, I found that two of the nuts had come loose—which can be very dangerous. I recommend carrying a 17mm wrench with you or using a little "LOCK-TITE" adhesive to prevent accidents. These are NOT lock nuts!
