I read somewhere that the iPad tends to slide out of place in this case. I am using a simalair iPad case that uses the same sliding system and don't have that problem at all.
It is in there really firm and can not slide out of place very easely. iPad 2/3/4 Carbon Fiber Look Flip Stand Leder Hoes (Zwart) (SH101289) - Superhoezen.nl
Maybe the iPad can be fixed with a little piece of velcro if needed.
