Did the keyboard bought 10 "device for a Medion and lo and behold it fits .... The adjustable knobs on the sides fit into my Galaxy Tab II, and thanks to the USB connection and a quick use was immediately possible. The envelope is a (albeit plastic) nice accessory and protect both components from unwanted collisions with existing objects in bags, such as keys, cell phones, pens, etc ... Of course, as a projectile and fall protection unsuitable !!! The adjustable straps are brought about "rubber bands" on voltage and allow a variety of models with thicknesses of up to 12mm thickness "clamp". The attached support leg on the back cover that magnetically on the bag and can put up a tablet when required as a laptop. Of course, this post is a little shaky in this price range, but it fulfills its purpose at office applications I do not know how many USB cables are required for direct connection to a tablet? In our tradition, the cable has a usable length of about 34cm without plug, that's enough loose for a 10 inch device ... The Tastaur has in my opinion, everything should have a small universal Tastaur, function keys, switchable keypad ... The keystrokes are good, also give some feedback and layout is in German! Ok, plug and play is not, you must make an adjustment device, so that umlauts and characters really agree, but that have hinbekommen even my kids. Conclusion: Cool part for real little money!
