Good haptics, shell but much too narrow for Lenovo Yoga 10 HD +

For my new LENOVO YOGA 10 HD + (10.1 inches), I wanted a fitting, durable protective cover.
The details of the manufacturer and the customer reviews supported me to decide for this product.
After unpacking and the first attempt to push the tablet into the protective sheath, failed the same; after several cautious Try it went - where the lateral overlaps bow outwards.
I did not get it overnight so, in the hope that the material would stretch.
But this was also not the case the next few days.
Criticism:
- The dimensions of the envelope and the device are distinguished by 5-6 mm in width;
- The speakers are covered by the backup tape partially;
- The front camera is overlapped more than half by the shell, therefore can not be used;
- The shell does not parallel;
- Return Postage whopping: EUR 19.00
The only good thing: touch sensation, visually appealing.

Summary:
A protective sheath, which is advertised for exactly this device must comply with the minimum requirements - this was unfortunately not the case!
