I let me provide two cases of other vendors, only to find that they only have value your 10-12Euro although much more promise was. So these go back. Then a last attempt with the company Snuggling and I was amazed that this shell is offered so inexpensive and should cost about 40 euros normal. After two days of delivery time, also very good, then unwrapped the sleeve and could tell all the good which the manufacturer promises will also be held. Top quality, super fit and very good optics and what is very important to me also that the tablet ie envelope, must feel good when reading and doing it well. One thing is important, before the tablet is pushed into the casing, an external SD card should be inserted, it must first be done, since the sheath portion blocked when you open the aperture to dust during tablet !! Otherwise all connections make it very easy to reach and no interference with the images, ie opening also as very good. There is however in my view no rating trigger. So Price / Performance Top !!
