I had not known that has the vision Tolino a Wake up function until I read in this envelope it. Admittedly, I was skeptical about whether it works. But it works perfectly! If you lift the cover on, you can see the the Tolino is awakened and you can immediately start reading. Very comfortable! For this, the shell is very comfortable to hold and fits in perfectly Tolino, not to say "like a glove"! The green color turns out better than it can give the pictures back here. I'm thrilled and would buy this cover immediately!
