The design is surprisingly intuitive. You just align the middle groove with the folding joint on your HERO9, 10, or 11 and tighten it down. It allows for a quick transition between 180-degree flat shooting and a 90-degree vertical orientation, which is perfect for capturing unique perspectives. Just keep in mind that this is a specialized tool designed for naked cameras, as it won't fit if you have a waterproof housing attached.
