Overall this is a win. It feels great to hold, very secure without being sticky/grippy like a lot of cases. The design I was surprised by how good it looks in person. The metal flourishes match the metal Google used for the camera outline perfectly, which is a nice touch. The sliding mechanism is chunky and solid.
I only have 2 complaints. 1) cards can be difficult to get out after you slide the mechanism open, since they don't stick up above the lip and you have to sort of dig them out. I solved this by putting a folded bill at the bottom of the stack of cards so that they get pushed up just a bit, and it actually works well. Would prefer a built-in spring system, but this works, too.
And 2) the kickstand works fine, but it feels surprisingly flimsy compared to the build quality of the rest of the case. I think it'll be the first thing to break if I'm honest, but so far it's held up to moderate use over a couple weeks.
Overall, very happy with my purchase.
