The case is very strong and protects the corners well. Its a little tight which causes one of the top corners to stretch a bit. I think the case is designed with the expansion capability to assist getting it on the iPhone. It comes with a 3.5 mm cable to plug in to speakers however it does not fit in the whole in the case created for the cable. Disappointing since that is one reason a purchased that case as I thought they would be providing a cable that would work. I have not used the charger. However for the great price I have a good case.
