Actually, everything good, even if the shell smell quite strong, like a chemical plant.
Unfortunately, however, it feels like that, and that's the problem.
Haptic of plastic used is, however, unfortunately absolutely useless and it feels like a zillion years old nylon bag (where the fibers are spliced), extremely unangenehm.Damit I mean, I had each after handling, wash your hands to the unangenhme feeling wegzukriegen at the fingertips.
This is either on the plastic used, or on the release agent in the mold.
Therefore, the depreciation on 2 points.
Otherwise it would be (price / performance ratio considered) quite 4 to 5 points have been.
Too bad, now I hope it works it with the return.
Note: The two additions (pen and sheet) are fine.
EDIT: (Even if it has nothing to do with the product) with the return went smoothly contact with the seller. Amount was refunded. (Directly above Amzon return did not, "because the article contains batteries") response to mails was very fast and customer-friendly.
