Where there is light, there is shadow.

The tablet is easy to insert into the envelope and take out again, the elastic band closes very good. Since this fits tightly I feel the opening and closing as bit fiddly.

By the rotating mechanism, the tablet can also tablets on stand (in a position). This is for reading probably quite reasonable. Overall, the shell acts by the rotating mechanism felt rickety.

For me, the benefits of the envelope are thus also the same disadvantages. Unfortunately.

No-Go: The stench. Even after 3 weeks still clearly smell. Although I washed the thing in the sink. With proper hot water, washing up liquid and NEM Schrubbschwamm. This has the shell survived. The stench but unfortunately also.
Holiday with flights survived, while the tablet also protected well.
All ports and buttons (except for Micro SD and Micro-SIM) are free. The hidden slots I need in everyday life, however, not because the card once inserted and no longer be removed.
Value for the price of purchase. Without smell, it would be even better.

I advise to cheap accessories, in a sale the expensive accessories is not worth paying a no buyer.
