I used to be a big fan of the Black Targus classic backpack laptop bag.
My first bag, which I got it as a gift, surprised me with its durability so that it stretched my expectation to say that this is an in-destructive bag. My first Targus bag back lasted for 7 long years till I got emotionally involved in it. I thought that this is an ideal travel bag.
Taking that in mind I wanted the same Black Targus classic backpack laptop bag, I got it from Amazon website from London. To my surprise, my second Targus bag started showing signs of wear and tear within to days of rough use. The back straps stitches started to come out.
I was surprised how vulnerable this Targus bag is. The first impression of the in-destructive bag was tarnished and this was no more my favorite bag. I got it for £35 in London and now I regret that I overlooked other good brand bags like Timberland or Adidas. It is not a dependable product as I thought it was. My advice is not to use Targus bags for traveling just use it carry your laptops.
