Great design and well constructed for the most part, but I find the buttons are very difficult to press. Maybe mine is defective, but they're virtually flat and unless you have very sensitive fingertips, you would not be able to distinguish them from the equally smooth bezeled area around them. The buttons barely protrude a fraction of a millimeter, so I find that half the time I have to look at where the buttons are and press firmly down or use my fingernail to press down. There is next to no click feedback on the buttons so I only know I've pressed then by visually looking at my phone to see the power or volume change.
Other than that one drawback, the case is amazing. Works well with magnetic mounts, and seems to provide very good protection so far.
Hopefully any future reiterations will have an improved button design.
