Any video taken by a phone at a show will likely result in a shaky footage, which is why the AirClip iPhone Camera Grip was invented by Mike Linhardt of AirCastMobile.
The AirClip iPhone Camera Grip is basically a plastic holder that secures the hand in place when taking a video/photo. It's a snap-back design that slides into the lower body of the smartphone and is easy to remove. On either side are two rings to slide your index and pinky, which allows for a more natural feel. Users can also enjoy portrait or landscape mode depending on their preference. It's easily transportable due to its small size and is a great item to have for taking decent pictures/videos on the mobile.
