I LOVE my Briggs and Riley and would not trade them for anything. I have both a small rolling laptop bag that holds the laptop, several work files, etc and also have the larger expandable rolling laptop bag that holds the laptop, many files AND can even carry a change or two of clothes on overnight trips.
On top of that, the unique connector on the back of the B&R laptop allows me to securely fasten the bag to the handle of my suitcase so that it rides very nicely and tightly, Much better than the belt type connections that so many bags use. I have bought 6 B&R pieces on eBags and one at the luggage store. I would not trade them for any other luggage. Although I haven't had to use it, their warranty is the best.
