As the saying goes, you get what you pay for. When I first bought them through Revain I received all 24 locking pins but the packaging was open and the spline was missing. The Revain box it arrived in was in pristine condition. However, the actual product packaging was opened and the tool was missing. So I requested an exchange from Revain and was assured my package would be delivered the same week. It's been 3 months now and Revain can't find my package. I also have a small issue with the security of these rivets. Are these supposed to be anti-theft devices? I've been waiting to replace the upper arm since I bought it because I couldn't find the right key. So yesterday I tried to break the bolts with a 19mm hex head successfully. This kind defeats the purpose of being locking bolts.
