THE ORIGINAL adapter that allows for the continued use of the iPhone 5/5s and Apple's universal dock or other accessories that use a standard universal dock connector plate. The Lightning to 30-pin Adapter from Apple is required.
In addition to allowing the use of older 30-pin accessories, it raises the iPhone to a comfortable height for using the phone while still docked. There is also a relief to provide easier access to the home button. Finally, the top surface of the adapter provides excellent leverage for removal of the iPhone from the dock.
UPDATE: This adapter works great with the iPad mini. See pictures above.
