The tablet is held by four corner loops close-fitting in the sleeve, which are designed in each case twice. On the one hand Tablets of various sizes can be fixed, but on the other hand one can also be a corner a little freer to keep controls accessible. So I use it: two corners are maintained with double straps, two corners with simple suspenders because there once located on the narrow side of the main switch of the tablets and diagonally opposite the "back" button, which would otherwise be easily concealed.
The case provides plenty of space and should cope even with really big tablets. My Lenovo A2107A (almost identical external dimensions as the Nexus 7) sinks a bit in the shell, but I do not feel that as a disadvantage. It really is very well protected and the material is very soft and hinders the use in any way. Additional pockets for memory cards or accessories, there are not, even if something is mentioned in the description. One might put a pencil through one of the smaller loops. But provided is nothing like that.
Included will be a "cleaning cloth", but that is a relatively rigid plastic piece with side-applied microfiber. For me totally impractical. I just put a normal lens cloth under the tablet.
Small drawback: The zipper can indeed be connected at both ends (so no matter which way round the lid is folded), but he is often when closing a little stiff. This is not the zipper itself, but on the slider handle and its attachment to the slide. Every now and then wedged the slide and is not being guided along the seal but slightly tilted (I hope this was somewhat understandable). Ultimately, the closure clamps and then it just goes after some back and strutting and little wiggle on. So far I have seldom time managed to close the shutter in one go.
All in all, four stars for the shell and clear recommendation for people who hold the tablet often and long in his hand: the loop relieves enormous!
