This neoprene case fits perfectly on my XMG A704 (17.3 - rump is quite thick, about 4 cm). The zipper works tremendously wertig, there is also no direct contact of this to the laptop, so no scratching risk. In return, the zipper from Case Logic is much more cumbersome to use. Once he is inside it still draws two corner tabs on these to get a better grip and protection. More details can be seen in my photos.
The smell is still in order. You can tell clearly when you enter the room, that a "new" object in the room. He is not unpleasant, but certainly not healthy. (NO pungent acrid smell!) The laptop takes the smell in a very short time to. Let's see, maybe I'll leave it even aired or throw it in the washing machine.
In itself, highly recommended, a few more washes it could tolerate but quiet.
