I got the part for my Acer Aspire E5 (17.3 inches - very flat) buy. The notebook fits with gentle force of width and bottom of the notebook compartment, of the depth it is clearly out of the bag, close the zipper is thus impossible. I've got it again with a 15 incher versucht- so goes it reasonably. That a 17 Zoeller matter to fit in what Herstellers- here, I can not imagine any. But seems in some yet to work ... or I have a broken-in model caught :). A pity, otherwise makes a good impression. Goes back, of course ...
