The Sticky Pod base is an aluminum plate with suction cups on the bottom. The center has the mounting thread where the extensions connect.
The extensions come in two lengths, three inches and six inches. They are made of solid aluminum. The knuckle connects the camera/camcorder to the extension has a rotating head that can twist in almost every direction. An included rubber washer will dampen some of the vibration between the Sticky Pod and the camera/camcorder.
Since the base, extensions and knuckles all use the same thread size, you can chain them together. This is useful in getting some interesting shots.
