The dock in question is well designed, with lots of small transparent plastic support to rest the iPhone secure.With this accessory you can also see the LED indicator that shows when the iPhone is charging.Price $ 19.99, is compatible only with Windows PCs.Note: Do not ask me why you see the holes on top and because of the SIM input is the opposite. But I think it is an iPhone clone or a product demo sent to the manufacturers of the iPhone.
