I approached this purchase cautiously, and have been pleasantly surprised. The suitcase is indeed light and easy to roll - though use on carpet generally requires tipping up onto 2 wheels and pulling like a convetional roll-aboard. The bag has dimenions roughly like a 22" conventional roll-aboard because of the wheels completely protruding from the bottom, but it holds significantly less than a 22" because the actual case without the wheels is more similar to the size of a conventional 20". If someone is looking for a suiter, this also lacks that. Overall, though, I was pleased with the amount of usable space. I have been trending more toward rolling my clothes anyway instead of folding into a suiter, finding that they wrinkle less. The separate zippered compartment on one side of the suitcase really facilitates that, keeping clothes in that compartment from being crushed by everything else. The other aspect that took a little getting used to was sitting my over-stuffed briefcase on top rather than using an add-a-bag hanger. It's a little unstable so I have to pay attention to keep it from falling over, but as long as I take care to pull the bag in the direction away from the direction it wants to flop, and as long as I am careful to make sure it's stable when I stop pulling, I can make it work okay. The biggest deficiency I noted that I think Tumi really should have designed better is that there is no handle on the long side. All of my other suitcases have that, and it's a big help for putting bags into an overhead bin and retrieving them from the bin. Hopefully they will address that deficiency in a product update.
