Got mine yesterday.
I ordered a lime green one. The bumper part looks nice and feels a little bit cheap. Compared to my official yellow one the plastic feels a little cheaper and softer. If I replace the buttons with the original it feels great. The buttons that came with it are a little loose. The TPU part does not fit my phone, which is a bummer but I only really wanted the bumper part anyway. Since I got a color that spigen doesn't officially sell, I am happy with it, but if you are looking for a color that spigen actually sells, I'd say go the official route.
