If the fit of this phone cover was better, I would be quite happy with it. The colour, design and feel are all fine, and it offers reasonable scratch and impact protection for the sides and back of the S3. However, the fit is so tight that it presses the "Volume Up" button on the side of my phone all the time, which interferes with its operation (and will wear out the button very quickly). I tried manually stretching the case a bit to loosen it off, but after a few seconds of being fine it always tightens up again and presses the button. It is so tight in fact that removing it often pulls the back panel of the S3 off completely.
Therefore, I won't be using it myself and can't really recommend it, although loads of other reviewers seem happy with it so I guess I was just unlucky with a bad batch.
