I made the choice of the four-star rating because everything is perfect has put himself who am .. the seller said that all the available button yes this is true ..sauf that after removing the original shell to put that of this case it is available as a button are either naked and unprotected ..a Read the button start / stop and the volume button which can have a long term effect and can be the damage to the contacts ..... !!! not always the hand Personally I protect them with a thin small silicone sheet material before sliding the device into the hull of the case and all is OK has put this beautiful cover damage inconvenience no protection because everyone is handy !!!
