All buttons function perfectly and the jacks and speaker are fully accessible.

I have had no issue with the case obstructing the headphone jack, and other than the aforementioned scratches, no significant damage has been inflicted on the case

Zero issues with plugging in even weird headphone jacks and phone chargers, and mic/speaker quality isn't inhibited in any way

This does not protect headphone or lightning jack on bottom

The audio jack and power port also get a little dirty

Besides this I'm pretty happy with it, let's hope it protects the phone as it says.
