Phone and tablet together: the 2-in-1 clamp takes a phone and a tablet at the same time, with one-click stretch buttons on both sides.
6-22cm clamp: spring-loaded, fits iPhone, iPad, iPad mini, iPad Air, iPad Pro, Surface and Samsung Tab.
Two 1/4in threads: on the side and on the base, so it mounts to a tripod, a monopod or any 1/4in support in portrait or landscape.
Cold shoe on top: add a microphone or a small light without another bracket.
Charge while you shoot: the base is cut away, so a portrait-mounted phone still reaches its cable.
Soft on your case: silicone pads on every contact face.
Pocket size: 64g and 8.2cm folded.
