Really pleased with these cases, one in all black for a 4S and the other white/black for a 5. Look good, feel good and great fit for both phones. They are solid and will certainly protect the phone if it's dropped. Easy to get on and off but they fit snugly and feel part of the phone. The + and - buttons stand proud, as does the on/off button on the top, which makes them easy to find but they still require a deliberate push to use them and are unlikely to be pressed accidently, so another positive.
These are a bit chunky, so if you want something slim-line or dainty I'd look at something else. The back is slightly thicker than the cover this replaces, but that is great as far as I'm concerned. It gives a good, solid feel to the phone and is ideal to hold when either using it as a phone or for typing on the screen.
Best phone case I've had and at a great price.
