I installed the eBay version of the rox pivoting risers over a year ago. Happy to say that there have been no issues other than having to tighten the bolts a little after finding the smooth contact surface would rotate in the factory clamp points. I’m sure the additional bolt torque is probably a death sentence for me with these cheap Chinese bolts and crappy pot metal. I’ll stop in every year or so just to let you guys know how they’re doing. I’d hate for you to worry.
