Well I've got the Andar case on my 13 Pro this morning. I have to say that I'm more than a little disappointed after all of the raving about them on this forum. There seems to be some sort of residue around the camera frame which I've mostly been able to remove with a SIM ejector tool but there's more there and I feel going any further will damage the leather.
Also regarding the camera frame, I was under the impression it was metal and it's clearly just black plastic. There also seems to be a chip in the finish on the power button that catches my eye every time I look at the phone. Then there's the volume buttons... why are the so small? It looks awkward. And the most egregious, and likely the straw that broke my back, is the inconsistency of the visible steel frame around the screen. The top and left side are exposed, with the top left corner being slightly more covered and the top right corner is completely covered along with all but the bottom inch and a half of the right side. It just looks sloppy in my opinion.
The real shame is I removed my Nomad skin thinking that was the problem.
