This smart set-up allows you to perform swoops and curves depending on the angles set for the wheels. The miniSkates System includes dolly wheels and frame, flexible GorillaPod SLR-Zoom tripod, and the Ballhead 1, perfect for point-and-shoot cameras and camera phones. The included Joby Griptight phone mount also enables camera phones to be attached to the rig quickly and securely.
