Re: Otterbox Defender
I can also testify that the otterbox defenders are an excellent protective case for the large part. I've had one on my iFruit 5s and 6s since getting them, and the phones are in near mint condition despite having been dropped onto tile floors, banged around, and somewhat roughly handled. I'm actually on my second case for the 5s after breaking the main latch on the previous case.
I will also state that the particular Samsung Galaxy 5S I had was special- it survived getting flung into walls twice when the Thing that was my boss at the time pissed me off. (both times the unit flexed enough that the back and battery popped out, but the phone itself survived with a couple scuff marks on the side of the case. The screen remained intact much to my surprise.)
