If the product is not super sexy appointed, he perfectly performs its function of remote controller: 2 large buttons in place of the controls in the gopro, allowing even with gloves (for those who will use it to ski for example) easy maneuverability. The camera can remain fixed on its support, not that we have to take between each shot. Contrary to a comment, this remote control is perfectly compatible Hero 3. A must for every owner of GoPro. Comes with a ring for the set key fob.
