Processing:
The shell is generally very well made; the edges are well stitched. It can be seen no irregularities or other unclean places (because there are none).
Functionality:
The shell is made accurately. The Kindle is well received by the shell and is securely attached. The Display area is not affected. The buttons are all easily accessible; the ports (headphone, Micro USB and Micro HDMI) are freely accessible. The Kindle erected, stand firm.
The price / performance ratio of this envelope is for me perfectly fine. Other cases have not convinced me.
A small downer but there is: I miss the tab for the touch pen stylus. The pen holder should now be standard. For this, I would deduct half a star. it does not work. So I forgive (still) 5 star because the shell altogether convincing.
I can recommend the sleeve.
