The downsides are that:
-l'image is not consistent with what I received (not so unfavorable, blue jumper and blue back cover, however, mark the bottom right and depolarized strip);
-the product - probably because it does not fit fully in the image - is not refined enough, impossible to hold the strip on the magnet, the kindle in a hull too far. Also the bar is an iron that attracts sooooo little magnet. This can be unpleasant and pose a risk to the safety of the tablet, what is search first. On the other hand, it imitates the books in which there is no magnet. ;)
