Needed a POV Chin Mount Holder for my HJC i90 modular helmet and acquired several. This is the one I have used for the past few months. It’s a K&F Concept Action cam holder, in my case I also used my K&F Magnetic Quick mount for Action5 Pro cameras.I am surprised easy it is to install, and more importantly how stable it is holding A5 Pro. The extended strap had no issue going around the chin bar and over the breath guard. Initially I had my doubts about it working, but after use, I am floored how well it works. I’ve tried both lengths of prong extensions, both short & long. If I use the long. If I place the mount up just a smidge, I can have the straps go around both side of the chin bar and the release operates fine. The rubber protects the finish of the help as well. You will notice I can’t shut the face shield all the way, but I typically ride with it at the first indent, so no worries about that, unless it raise, then a little rain gets in. If I really wanted to center the lens, I would use my RUMSEM chin mount adapter prong extension, and it would be perfect, which is also part of my motorcycle kit, Maybe K&F Concept could include that kind of mount for perfect centering.I really like this ABS resin mount. I am adding this K&F Concept Action Cam mount to my motorcycle camera kit. Thank you K&F Concept!Great value for money. Fits my HJC i90 modular great. Good piece of Kit.
