i have to say, ive had this bag for a few month now, and i use it every day, there are no signs of the seams starting to rip or any other signs of poor build quality. o think that this is a brilliant bag for large laptops, as it is very hard to come across a good bag for big laptops for a price like this. i have to say that i am very impressed with this bag.
 

This bag looks great. It looks like a laptop bag, admittedly - it's not trying to disguise itself as a briefcase, a small suitcase (although it's the same size), or, you know, as something otherwise subtle. But it's voluminous, BRIGHT RED, has lots of compartments, carries a lot of business paperwork, plus cables, plus a laptop, very safely. No complaints on any of these fronts. But the one I bought, in less than six months, has started to come apart on several seams, none of them load-bearing (ie, so the weight of my work has not had anything to do with this failure of manufacture). A real shame, as the bag was otherwise working out really nicely. I'd really counsel caution in buying this (or presumably any other Techair products) if this is the general standard of their build. I've come onto this site looking for a replacement, and thought I'd warn you all about what I'm replacing.
