The Book Books are processed simply beautiful and excellent. I have one for my iphone for several years, which is even located just one hour in a lake (accidentally!) With no visible traces! This BookBook is fun to hide it on the shelf between books or simply to have in hand. It is built solid and functions as par. To close the fairly solid zipper needs to be drawn to the iPad once. This makes it stable closed, where you can close other cases simply, without being sealed.
Not optimal: The iPad is secured with 4 press studs, must be resolved by those two to get it set up. Looks, however, from solid. The iPad is not deactivated when closing the door, as it is known from other Covers. Plugging in the power plug is not always perfect, because the hole in the leather so big is just like the plug and the plug must be plugged through.
Conclusion: a delight for lovers of beautiful things. Practicality OK.
