If you are late for a plane, grabbing your bag and trying to make it through the airport fast - this bag is for you. Slick wheels and light.  I bought it before a trip to Singapore based on the recomendations from this site. It is well built, has plenty of storage and has held up well for several other voyages.
Only caveat - it does look like everyone else's bag, so figure out a way to make it stand out to recognize it at baggage pick up.
