I have used a number of sturdy protective cases. i will not mention names but they ALL worked well initially. This otterbox DEFENDER is impressive. It makes my iPhone feels safe & secure, and looks like will it last the distance. (lets hope so !)
it depends what you looking for ,but i looked at the COMMUTER which was ok but the Defender is THE business. It is worth the price, if the info and functionality of your iPhone is crucial. well done otterbox. I will get back to you if it does NOT last the distance
I have used all functions like Speaker Phone SKYPE call and the case did not affect the call
THe silicone case is robust & well fitting.
