I have looked for a matching envelope here a very long time and this had me very interested. Above all, I was looking for something where then strain after a while no great signs of wear can be seen for example when the tablet is by rubber bands in the shell and then but could ausleihern sooner or later. When you first use I was very pleased with the shell. The lateral setting up was also no problem. Unfortunately, the upright-installing is not as stable as the horizontal setting up. It must also be noted that the Tab is an extra shell and is then secured with Velcro to a second shell and so there is such a book.
