The flip style is useful, front cover has a nice feel to it. Both logos on the front are done well. The back however is awful - the plastic is very cheap and not trimmed well. The catches connecting to the case are poorly moulded, causing the cover not to fit fully, leaving nearly a millimetre gap in some places. Colour is not very well selected - blue-grey, making it look cheap. I bought it for my black S3 and it doesn't go well with it.
There is also no magnetisation of the front cover, meaning it doesn't stick to the screen when closed.
Bottom line - poor quality for an expensive, official product.
