Good cover, with some bad inclination degree

I use my tablet most of the time in the university and transporting it so much. Have decided to use this envelope, because it is very chic. In the lecture halls, the tables are a bit slanted, which makes it impossible the tablet in "upright" position to position. Also during transport, the lid goes on often (somewhat weak magnetic) and thus turns the tablet.
Otherwise she is very smart, but a little hard.
