The case has different material in the front and back, the front is glossy and almost transparent while the back is more opaque and it is matte. The holes in the back are about two mm off center. The big one is just a little ugly but the hole for the flash covers about one third of the flash which is unacceptable. The seam is not of very good quality and doesn't feel very nice to the touch.
The front part is thicker than the original Nokia one, but it doesn't interfere too much with swipe. The top part is completely open and makes inserting and removing the phone easy. Also the comparison with the original one that comes with the device is unavoidable and the original wins in every aspect.

The N9 is a beautiful phone and there are many features missing to make those stunning looks possible. Don't spoil it with this case.
