Depends upon how much you care about your signal reception. Not supposed to be as big of an issue on the Pros vs the Vapor 4s. The metal bumpers look sharp, but again, I'd want something with more shock absorption for the back glass panel. I feel like the shock from a drop would just transfer from a metal bumper directly into the phone's frame sans backpiece or cushioning. Then again, I'm kind of biased against bumpers in general because of this concern.
TBF shock protection wouldn't be on the top list of priorities for anyone purchasing an Element Vapor case.
