PROS: I took this bag on a 2.5 week trip to Europe where I had to carry it up and down staircases in train stations. I'm a small, senior woman, so I needed something that I could handle easily. This bag was great. It was very light weight and packed nicely with packing cubes. It was easy to get in and out of. I love that is stands on end without tipping, and holds its shape when empty, packing and unpacking. It withstood the long flights between Europe and the West Coast of the US - with baggage changes at JFK - and came out looking like new. Great purchase.
CONS: For a 2 wheel bag, this maneuvers quite well. I'd love to have 4 wheels, though. That would probably make the bag heavier, though, so it would be a trade-off.
