The cover feels sturdy and strong, and it also features handy magnets so that it stays fully open or closed and doesn't just slam against the e-reader. It feels really good in the hand and fully protects the screen. Even better: the e-reader automatically goes into sleep mode and wakes up again when you close or open it.
The design is SUPER; instead of having a large case around the entire e-reader, you can simply remove a section of the e-reader, which then acts as a connection point for the cover. This makes it look super modern, and it remains almost as thin as without the cover, but with its screen fully protected.
However, installation can be a bit tricky: the section you have to remove from the e-reader is really firmly attached, which made me a bit afraid of breaking it. I would recommend looking up a YouTube video first and then carefully removing it. Fortunately, this does not apply to the cover itself, and in principle, you only have to do it once.
