As the envelope looks, everyone can look at the photos provided, they are reality accordingly, all the details are clearly visible. So you can see in advance what you are getting. The protective cover is relatively thin, which has the advantage that the iPad is not much bigger, but retains its elegant, slim silhouette. However, some at the expense of shock absorption. In detail:
a) the protection: is ok, passable shock-absorbing material. But probably not enough to make a good piece consequences fall from table height onto a hard floor. But much better than no cover. 3 of 5 points.
b) anti-slip: The shell is slip-resistant. The skid resistance increases, the handling is improved. Test: the tablet once with, once placed without cover on a flat surface and tilted it. Without envelope truly captures the very smooth tablet without envelope much earlier to slip. 4 of 5 points.
c) the cut-outs for switches, plugs and speaker / camera / microphone: These sit at the right places and are adequately dimensioned. Very nicely done. 5 of 5 points.
d) ease of installation, strength of the seat: The shell can be relatively easy to coat, but then is tight and perfect in my opinion. 5 of 5 points.
e) feel, smell: all right, no foul-smelling chemical bomb. 5 of 5 points.
f) impairment of the tray to use: I could not tell. No accidental switch activations. 5 of 5 points. Should this happen to someone, a tip: you can the material very easy to edit with a sharp utility knife, and as the field on the on / off cut. But it was not necessary in my case.
Conclusion: If you want to have a thin, stylish protective case for your iPad and SmartCover not used is black right with iProtect TPU Gel Cover X-Line. In addition, encouraging low.
If you want, however, have a perfect protection for union experiments on hard floors, which I recommend to the (however currently more expensive) model "Snuggling iPad Air (iPad 5) Silicone Case made of black, non-slip material. Protects your iPad and feels pleasantly soft ".
The "Snuggling" makes the iPad much bulkier. So you have to weigh up what is a important.
