Me? I bought sienna brown first, and then bought Taupe. And no issues so far, no gaps,perfect fit, perfect leather feel and perfect clicky button. Cutout is Bullstrap-type, is nicely done, seems sturdy enough. Taupe blends perfectly with natty and dessert titanium, and Sienna brown is just a beautiful color. I kinda like more Sienna Brown as a color but Taupe just blends perfectly so I have mixed feelings haha.
I think (not sure) that the key is they use a thicker layer of leather(compare to RL closed bottom for example), so you can really feel that is leather and not plasticky feeling, that’s what (for me) makes them to be up there on top, at the same level if not best than Bullstrap and RL Open bottom (this 2 are also for me, really top choices)
