I have loved my Otterbox cases in the past and was both surprised and disappointed upon receipt of the iPhone 5 Commuter case. The rubberized and hard shells neither fit well with each other or the phone. There are obvious gaps between the rubberized body and the device, negating any 'dust and particulate' protection attempted. The buttons and ringer toggle are difficult to operate, and the port covers simply don't fit the hard shell. As another reviewer stated, there is a slightly sharp edge on the face of the hard shell. The rubberized shell looks like it's years old straight from the packaging, with frayed bits of rubber, odd creases, and weathering all over.
I would neither recommend this product to a friend nor purchase it again for myself.
