But then I noticed something: my Kobo discharges at a rate which I would not have thought possible ... Wanted it therefore trying times without shell and had the take out of Kobos notice that the soft rubber backing has cruelly discolored in Pink. Just looks ugly and I am very very disappointed. My Kobo saw times from really chic and the whole point of an envelope was to protect his appearance and not to ruin it.
In addition, the envelope got scratches and dents quickly despite careful treatment.
My conclusion: It was an expensive lesson that has tasted suspiciously low price. Clear recommendation not to buy this product.
