The material is good, but the cut is bad: the cover exceeds the iPad 3 to 5 mm. In addition, the hinge system is the iPad 4. However Air iPad for which this product is sold has a different profile than previous iPads (Air is thinner and edges more "square "). Hence an important game that by taking in hand the closed iPad, you hear it lock and unlock intermittently.
In short, a bad copy. Yet it should not much adaptation to make this perfect product: a magnetic hinge adapted to the iPad Air (actually the real hinge of the Air is very simple and crude as the iPad 4, so they made this cover with old designs) and a cutting to size.
