My cases came in from Stylzworld.com today, and overall I m very impressed with the quality. They are a bit heavier in weight than I expected from the other cases I have reviewed, but overall it isn't much of a hinderance. Stitching is very well done, and the holding system very secure. I especially apreciate the fact that there is about a half-inch above and below the Kindle to help prevent from accidental damage, something notably missing from the other cases I have aquired.
Of the two the Avant Garde is definately more masculine. The Kosmo has a jarring lime green as an internal accent color for the pockets, definately giving it a more feminine look, which is actually disapointing to me, as I typically prefer a natural leather look to black.
I will update with pictures tonight after work, but aside from the long wait time, I don't think anyone who took the risk on this case will be disapointed.
