A great product that allows to any phone on a dock. That way, if you change the phone and the cable connector is no longer working or that the manufacturer change it from himself (iPhone 4S to iPhone 5), the dock still working fine and we do not have to buy everything. The dock itself works perfectly and the principle is really stunning. The phone is hooked and do not fall off when pressed but still comes off easily when you want to take it back. A very good article that I highly recommend. It works even with a shell.
