I've always loved Otterbox stuff, and this Preserver is no exception.
It performs exactly as expected! Sound is great, camera quality is not changed, TouchID works the vast majority of the time.(~85% or so)
One thing to keep in mind with TouchID, remember to retrain the phone once you install the case. You press the button a bit differently with the case on, so you want to remap it just to be 100% sure its good
I took the case down a local river with me while kayaking, and put it through it's test. It held up to swimming, rock climbing, various drops, dives, jumps from bridges, etc. This case is awesome!
Pros: High quality, Durable, touchid accurate, no sound issues
