The slip cover is a great value add as it is a phenomenal shock absorber. However, it gets discolored very easily and is impossible to restore (to my knowledge).
My iPhone 5 case broke at the charging port (I don't know why or how) the phone remained safe so no harm no foul. Otter replaced the shell at no cost, good for them. I wish the charging port was a bit longer so the after market adapters would fit without taking the case off.
I had a small problem with my otterbox product but the situation was resolved quickly and very easily. Great warranty, website and personnel. Would recommend and purchase this product without any hesitation
