In terms of disappointments, it may be noted that the perimeter of the back is quite ugly plastic with leather imitation only in the central part. Moreover when the casing is closed, the valve does not wedge well but is shifted one half centimeter and a little beyond. It's a shame.
But more troublesome is the magnet that is used to automatically turn off when you close the Kindle: it is so powerful that the Kindle also turns off when the valve flap on the back to read! This forces us to be careful how you hold it, otherwise the reading is regularly interrupted by the screensaver ...
As for the screen protection, it is not enough mate and makes painful reading when backlighting, I removed.
Anyway I'm pretty disappointed with the product, I would have had to opt for the official case.
