Summering: I purchased this laptop bag for my 17.3" laptop. It fits great. I also liked the extra storage space. For cables, wireless mouse, etc... I would recommend this bag to anyone with a 17.3" laptop.
Summering: It was unclear if a 17.3" screen would fit into a case marked 17" so I bought one for 18". The case is at least 2 inches too big in both directions. It is also very stiff. Because of this, it fills up very quickly. Once the bag is full, my liquids bag for airline security fits too tight into the outside pocket so it has to go inside. It would be ok for just a laptop and papers but not enough room for other stuff. Not a good carry on briefcase.
Summering: Had to choose between a Slimline case and this Case Logic one. Read reviews and too many negative comments on Slimline one not holding adapters, etc. This case is super and very well made. Laptop is safely secured inside padded area with room on the side to carry power adapter and cords plus mouse if need be. Outside zippered area to hold files, CD's what have you. Ease of use with carry handle or shoulder strap. Glad I bought this item. Very happy with it!
Summering: I have a Dell 17.3 laptop and it fits perfect. good quality, plenty of easy storage. I like the way it unzippes on 3 corners top and bottom compartments so you can sit it in the case and not have to slide it in. am very pleased with my purchase.
