Fit / feel
The sleeve fits my impression, very good (not too tight or too loose). They can be attached easily and also makes the "problem sites" (for example, upper left corner - in the upright state - between recess for Smart Cover and earphone input) a stable impression - not have cracks etc ..
The recesses for various openings and operating elements (speaker, earphones, Micro etc.) are worked exactly. Only in the rear lens the symmetry is not quite given. The recesses for the original Smart Cover from Apple are available.
Compatible with Smart Cover
The function of the Smart Cover from Apple is given (I myself use the Air no Smart Cover, but it can test with a borrowed).
There is another iPad Air is the extended family environment with the same envelope, to me two things are noticed: even the soft touch surface feels the two Belkin Cases definitely different to (even blunt - one much smoother), and the inclination of skin moisture ( show sebum) on the back cover as patches, in which a back cover given clearer and the other not at all. I have the impression that there is a certain series dispersion in the material used (?).
Conclusion
Overall, I am convinced of the cover and it can only recommend. It fits well and gives the iPad while keeping a good grip.
Should there be any problems during long-term use, I would complement the review in any case and report here.

Protect Even after almost a year and holds the back cover as the day (no stress cracks or similar).
