Bought this as part of a plan to revitalise my flailing S3 and give it a new lease on life.
This cover does an excellent job. The finishing is superb, given the price, I went with the Black/White combination to compliment my white S3. The outer rim of the case is made of a malleable, but very sturdy, rubber-ish material. The back face is made of a different material and features a cross-hatching design.
The cover fits snugly, but remains simple and easy to remove. If you replace your batteries by removing the back cover, the case seems to have a small cut out in the top left corner of its back to assist the user in dislodging the back with ease.
The cutouts around the key areas (charging point, headphones, camera, etc.) are all crisply cut and have not presented a single problem as of yet.
My only gripe would be the fact that the power button and volume buttons are also enveloped in the material of the outer rim (rubber-ish), thus I feel the buttons appear to have increased sensitivity as a result. I'd prefer to actually feel the buttons of the phone. Mind you, this is simply a personal preference, and I can understand the manufacturer has designed this to ensure a consistent design.
In terms of drop protection, this cover has performed reasonably well, but then again all my previous covers have somehow managed to protect the phone. I'm not the kind of person who drops my phone constantly, so I'll refrain from commenting any further.
