So did I after reading your post, as its only a matter of time when I would drop this beauty.
Arrived today.
My Quick Test drive so far. It makes the phone very very heavy, could double up as a weapon also.
The iPhone 11 Battery is incredibly long lasting in its own right, and really doesn't need the attached back pack. Bit of an impulse purchase.
Its very good quality material though.
I had one of those for my iPhone 6S+. Decent enough but the flexible part expanded and got loose over time. Disappointing for a case that cost €70 plus at the time. The iPhone was like new when I flogged it and yes it fell a few times with the OtterBox case on but suffered no damage cosmetic or otherwise.
