Love this bag! I use it as a carry-on when it is my only suitcase and also when I check a larger suitcase. It is very lightweight, and easy to maneuver. Very handy to turn sideways and push down the aisle of the airplane. It doesn't fit under the seat, but it easily fits in the overhead bin. I was surprised at how much the bag holds - it looks small, but holds a lot. Even fully loaded it is still lightweight. The retractable handle does seem a bit flimsy at first, but after several uses, no issues, and I have come to realize it is flexible, not flimsy, even with a heavy briefcase on top. I like the built-in lock, uses the same TSA-approved lock as the ones you add on, but don't have to worry about it getting lost.

I am a huge Tumi fan and had looked at this case a number of times before I invested. I am a frequent domestic and international traveler for both business and pleasure. My primary reason for purchase was to move to an upright (four wheels on the ground) type of bag to save my shoulders - mainly from the added weight of my briefcase full of electronics on top of my carry on. I was apprehensive about the size and cost - I should not have worried - this is another great Tumi product and holds as much or more than larger carry on bags. It also always fits in the overhead without problem and carries the weight of my briefcase without tipping while still rolling smoothly through long concourses. Note that it is also an easy roll down the aisle of an airplane.
