Car Mobile phone holder

I created the magnetic mobile phone holder for car by using "Ball-in-socket" mechanism Why ball in socket mechanism ? Ball in socket mechanism has three degrees of freedom, which is very helpful to use the mobile while holding in a holder, we can either rotate and forth front and back the holder , so I chosed ball in socket mechanism.. Why magnetic holder ? To reduce the human effort , I chosed magnetic holder, if we magnets to hold the mobile phone means we can easily access the mobile with holder and it's user-friendly.
