I've owned my Kensington - Contour Laptop Roller for a number of years. It's been thru heck & back! Out on mine-sites, overloaded most of the time, back of my pick-up truck thru all kind of weather, rolled thru some up scaled office buildings, you name it, it has served me well. I'm purchasing a new 17.3" high-end replacement laptop and bummed to see the Contour is out of stock! Hard to bring myself to purchase anything else.
