How does this work? It’s really as easy as 1, 2, 3. So we’ll start at 1.First you need to find where you want to mount your device. This will give you a good idea of the mounting attachment you will need. 2. Some mounts (like the Clamp mount or Fork Stem mount) need an adaptor to mount your phone on or if you want a different adaptor for your Action Camera with a flat surface and so on. Some mounts don’t need one and have an adaptor for your device on it. 3. Choose a case or holder for your phone, tablet, etc.. That’s it you’re done.
