The processing of Shields is really good. It also harmonizes beautifully with the Smart Cover. And especially important: The application - as well as the re losing weight - is a breeze. I know of other cases (including Belkin for iPad 2) which you again can separate from the iPad with a lot of effort.
Together with the Smart Cover makes this protective cover from Belkin certainly a good protection for the iPad and is also still visually appealing, because you want the beautiful iPad not "spoil" optically necessarily by a protective sheath.
One must, however, be clear: This back cover together about the Smart Cover is in no way suitable for harsh outdoor use, at best something so that no scratches come into the housing when the iPad is transported in a backpack or suitcase.
