I'm a fussy sod, so when looking round the shops for a laptop bag, I could never find one that I liked, at a sensible price or even one that would fit my 17" Acer 7520, so when I read the review about this one on Amazon I thought I would give it a try. Well, there's a pocket for everything, mouse, external hard drive, mains cable with transformers, ext cables. It has two slots for the laptop, my Mum has the same Laptop and I fitted that in as well. It's well padded and even has a non-slip net material, so if you put the bag on table it wont move about. The shoulder strap on my one is fully adjustable both ends and is very comfortable. Every time I open this bag I think 'What a bargain'
