Material very well what but this price may be. The state function with the rubber studs is well intentioned but it does not hold. Although the tablet is level on a table, it is not long until the holder tilts. Also you can see the pimple marks on the display. There is also no lock on the sheath and is therefore suitable only for the extremely cautious transport. The price is much too high and actually an insult for the zero function. I would NOT recommend this envelope.
