This is the issue with the rep. First of all,it doesn't fit with straight pins. I had to curve them for hem to fit In the holes. But then the strap does not sit perfectly tight onto the case. It kinda rotates and leaves a gap when that happens.
But if I keep the pin curve to minimum it's pretty tight and doesn't rotate under regular wear. Only if I push it like I did above.
All that said, I like the look of the rubber and he change of scene. I'll probably go gen if I can get a nice price on it.
