I have two larger Delsey Heliums and I love them. With the new 50 pound weight limit strictly enforced, I don't want to waste pounds on my suitcase! I bought two of the carry-ons to match and love them as well.  My only complaint is that it does not come with an integrated suiter. Luckily, I have detachable suiters from previous suitcases that work with this. I would definitely recommend for a carry-on or for a suitcase for a child that they can maneuver themselves.
