I love this - but unfortunately it doesn't fit the laptop I bought it for.
I specifically bought this sleeve rather than the many others on the market because it said it fit any laptop up to 17". However, when I got it home I found that there were more detailed specifications on the product itself, not provided by Play.com, that meant that my laptop was about 1cm too thick to fit in it comfortably.
So, for any potential customers, check the following dimensions for your laptop:
Max length = 392mm
Max width = 290mm
Max depth = 40m
It is a testiment to how cool this sleeve is that I'm keeping it to use with another laptop for which I already had a sleeve, rather than returning it!
