I've only tested the Pinclip mount in my house, not on the bike yet. But the connection seems really secure. I put one on my Gopro and on my floating handle, put the wrist strap on, and acted like I was throwing the handle as hard as I could across the room, and the Gopro was still mounted perfectly. If the gif attachment works then you should be able to see me trying to flail as hard as I can to get my bike light to break off, and it stayed mounted with no issue.
The only real negative is that the quick release mount adds about two inches to the height of where your Gopro is mounted. (Or if it's hanging down under your handlebars, it will lower the camera that two inches).
And if I wanted to nitpick... the included Gopro screw being flat instead of Phillips head means that my bike multitool can't be used if I ever needed to re-tighten it (it's knurled for thumb use, but in my experience tightening by hand is never tight enough, the cameras will rotate unless using a screwdriver).
But I anticipate this being another Fidlock product I can't live without.
