I really, REALLY prefer slim cases. However, I got this one mainly for travel, or days I know ahead of time I will need heavy use away from a charger. It came just in time for a week at Disney! Used on a launch day X. No issues with pop ups like others have noticed. Not sure about audio issues, as I really don't play external audio through the speakers much.
First impressions are that it is a quality accessory (I hope at the price!). It is heavy, although not terrible, possibly due to the balance, as the battery is low in the case. The way the hump sits makes it easy to grip. The lint attraction was noted and does seem to be going away.
I've gotten great performance so far. I have been making it through an entire day at the park (12 hours) with heavy use of the Disney app, camera and photos apps, messaging others in my group, gps app to locate them, etc. and only depleting the case charge and maybe 20% of the phone. The case fits decently in my pocket also.
But....this may be only an issue with my unit, but I'm having an issue charging wirelessly. I placed the phone and case on my wireless charger and left it overnight. I woke to find the phone was fully charged, but the case was only around 40%. I used a different wireless charger the next night and the same thing happened. This time, I noticed the charge light on the charger was blinking as if there was an error. Both nights the case was on the charger about 8 hours, so there was plenty of time.
I'm not sure if it is defective, but seems likely as I used two different chargers, both have worked flawlessly for over a year on the the phone alone.
