I bought this neoprene sleeve for Sony Vaio 13.3 "and I'm a little disappointed. Indeed, I found that the cover was a bit too wide and therefore the PC easily move inside. Moreover, neoprene ultimately not protect as well as the yet cheaper polyurethane slipcovers like The Wedding Be.ez. Here, one has the feeling that the PC is just under our fingers in the cover and the protective layer is too thin to protect the machine properly, while in The Wedding Be.ez, we really feel for an armor adorned foolproof and we do not feel at all the PC via the touch outside. Finally, a case of good workmanship (as usual with Case Logics), but less effective and more expensive than polyurethane solutions from the competition.
