Picked up a Bullstrap case for my iPhone 11 Pro, and, well, its exactly as billed. Luxurious, solid, deep color, nice in hand and with a real quality leather smell.
As far as the fit, its nearly perfect, and maybe some time will allow the bottom corners to nestle into the case a little more deeply and securely. For now the leather prevents a full, neat seating at the bottom as it does with apple's (albeit much thinner leather) case. Still its a very minor niggle that many wouldn't even notice.
When I first put the case on it was actually quite hard to get on, as well as the buttons being pressed in from the stiffness of the leather. But I worked the leather a bit, and pressed the buttons further out with my fingertips, and it was then seated well with perfect functionality.
The card slots are very neatly sewn on, and of course a little stiff. I found that the the rear case is tighter (obviously) than the front case, so I use the back one for the thinner metro card and the front for the thicker card. I bet with time you could add another card to the two slots, as the leather stretches with use and age, but for now Im using just these two essentials.
The lack of card slots in apple's case always bothered me, as it was inconvenient to carry a wallet when I really only need a couple of cards with me when going out for the day.
In all a full recommend for this quite nice, and quite beautiful iP11Pro case.
