I have seen this product purchased after my phone 2 times (harmless to my happiness ...) was dropped to. The product arrived as advertised and is characterized by excellent fit, relieved all sockets and all the buttons are pressed. Only the lock / unlock key pointed to attachment of the shell a "life of its own" when I wore the cell phone in my pocket. My mobile unlocked itself automatically. Case back down, direct amends. Apparently this little buttons is a little biased and thus appears to be a slight pressure on the body of the envelope to be enough to push the button ... A very nice solution if one does not carry the phone in your pocket with you, unfortunately, unsuitable for me.
