For Cases:
The sleeve itself feels very solid and high quality (surprisingly heavy) and protecting the tablet excellent, the mechanism for setting up is initially a little getting used to, but works perfectly in both locks. To fit, the Transformer Book fits neatly into the envelope, nothing wobbles and all control buttons remain easily accessible.
So all in all for the price of about 20 A recommended protective sleeve, I would buy them any time resist.
Why 4 and not 5 stars: a downer or small design flaw, the shell (one probably it was not because of the anderst cutouts for the speakers or similar). The middle pins are holding the tablet in the envelope somewhat unfavorable position, they lie when you close your shell is not in a depression which serve to erect the tablets but at a thicker padded place in the lid. Thus, the cover of the envelope is not completely flat on the display and bulges out slightly when closed.
