I have two otterbox cases for my 4s, the defender and the commuter. The defender is great protection but a bit heavy for everyday pocket carry, so I find I use the commuter most of the time. I have dropped my phone from 5+ feet on to concrete (unfortunately more than once). I have cracked the case...but the phone is perfect! The combination of the shock absorbing inner piece and the hard (and easy to slip in pockets) outside is unbeatable.
