If you ordered them from RBI, you should be fine. I have ordered them for years and they all seem the same except they do warp after a while lol.
Well, that's what you get for ordering from a middle man lol. That would be like me buying a Rolex from a guy standing out in front of a Rolex dealer saying his stuff is legit. If i can, i ALWAYS go straight through to the manufacturer. Do it with Herpstats with Spyder Robotics and do it with anything from RBI. Honestly the only companies i really order from are RBI, Spyder Robotics, AP and i usually just drive out to Bean Farm.
