I have purchased many otter box cases for phones and other products as well as worked in retail helping customers with these cases. for a defender series this is pathetic, the silicon shell wont stay on as well as it is not shaped or molded correctly to the shape of the polycarbonate case. normally i see this kind of problem with the commuter series, i have never seen this many problems with the defender series. I personally work with 6 people who all do have the defender case for Galaxy SIII. all of them (not the same color case) have this same problem.
Cons: Low quality, Not durable, designed as an after thought
