I recently bought a GoPro Hero 9 just to record my bike rides and use it as a "DVR" in case something happens. GoPro products were WAY too expensive for me, so I decided to look into third-party alternatives. Lo and behold, this $16 kit had the necessary chest and head mounts and more if I ever thought about it. The overall cost of the kit was much cheaper than if I had bought an item from GoPro. Can't comment much on the quality at the moment but it seems solid and will hold my GoPro in place.
