I use the travel bug as a purse and for that it is perfect.  The bag feels well balanced and the shoulder straps are wide and comfortable.  My only complaint is that the bottom is curved, not flat, and the bag falls over every time you set it down - very annoying.  Otherwise, since it's black and small it works perfectly as a purse with shoulder straps.  It's well-constructed and has all the pockets and compartments that I could wish for.
