In general I am very satisfied with the product, but I have to deduct a star. Although the tablet is optimally protected, the rear camera is free, and all buttons and ports, and even putting up widescreen works (almost) perfectly (on the last stage is there before me, that it tends to far and the Then tablet while typing umdrückt), but the tablet does in portrait orientation with the envelope less fun. I have very large hands and without the shell Thumbtyping was the portrait for me no problem. The envelope you have it, however, either as a book keeping open, or you work the "cover" behind the tablet, although a part of it poking out the sides and one thus has an additional roughly thumb-wide piece of leather in his hand. To dangle the cover just backwards, I feel personally, because of the balance, to be very uncomfortable, it is in my eyes so no real alternative. Since I use the tablet primarily for reading PDFs do not interfere with the book-like attitude, however. The SMS-typing has slowed, if not a table is available. Nevertheless put my tablet, because of the advantages in widescreen format, always in the envelope and who else can make friends so that who has definitely a well-made sleeve for his tab. The locking mechanism is actually extremely simple and not seen in the photos here: It consists of a finger wide rubber band that is stretched over once the entire height. This solution like it very much, because the mechanism is even half asleep, very easy to use.
