The good thing about the case featuring two sliding pieces is that the bottom piece can be removed for easy docking in things like speakers or Apple’s iPhone 4 dock. So, why is the case called the Reflex? Well, the video above demonstrates best. When the phone is dropped on a surface/item it has a small bouncing or rebounding effect. This not only ensures that the case will not look damaged, but more importantly will keep your iPhone 4 in pristine condition. Otterbox is known for their larger, Defender series case that certainly is one of the most, if not the most, protective iPhone 4 cases on the market. The Reflex case takes cues from the Defender, but presents them in a thin and light package that anybody would love to keep their iPhone 4 in.
