We just got our latest shipment of these products and they are already one of our favorite mobile accessories! EXTREMELY well-made and CNC milled from a solid block of aircraft grade aluminum. They work with ANY phone/device that is between 57mm - 87mm wide and within 12mm thick (see 3rd picture for diagram with measurements). The iPhone 5 is a perfect fit, as well as all other versions of the the iPhone Galaxy S2, Galaxy S3, Galaxy Note, iPod Touch, etc.
A 4th Design Aluminum Tripod Grip makes a great present for any serious photographer or hobbyist.
