I've recently purchased this product and I am just wondering if there are any faults, I currently have a 17" laptop to fit inside and the bag says it can fit 17.3" I'm just wondering if the measurements being close will it be an issue? Further the bag says it weighs two kilograms, my previous bag weight 250 grams does the weight make it an issue to carry? I know 2kg isn't a lot but compared to other bags, it's quite a difference. Any seam faults? Can it break easily or is it worth the value? Quite curious about your opinions as I was unable to really find any reviews elsewhere.
