This is a simple yet effective model, transforming your MagSafe adapter into something that can be mounted using any existing GoPro mounts that you might already have laying around. I had a bunch of the table stand plate thingies that you see in the photos, but it fits all the standard mounts. As versatile as your GoPro mount assortment allows.
