They contained two "quick pins" and were 95% non-locking. Stick them in the hole with the camera attached and nothing, no blockage. If you sit there and play around with it for 15-20 minutes you can get it to lock up at times, but I've given up as it ruins my pre-ride vibes every time I try it. It worked the first day I got it, now it works 5% of the time and on the last ride it was completely loose and just hanging around. Appears to be an imperfect design.
