The reason why I still give only 3 stars, is the smell.
I have ordered the shell just before Christmas and taken out of the plastic packaging on Christmas Eve. That is now already more than 3 weeks. The smell of artificial leather and chemistry was so unbearable on the first night that I had the feeling I am left off the air; so extremely chemically it smelled. I put the bag for 2 days on the porch. Unfortunately, that was hardly improving at the smell. For more than 3 weeks, the bag hangs in our (well ventilated) hall (outside I would have at temperatures below zero fear that the material is damaged) and there it airs to himself. The day before yesterday evening I have the Kindle trial once again put into the envelope and read a few pages. The smell is now only slightly noticeable, but still very uncomfortable. Conclusion: It migrates for another week in the hall, then tested again.
I recommend buying therefore only if one before use at least 2 months has to let them air out enough. Do you need it right away, I would advise against the purchase.
