Query: Best traveling investment to date!

I purchased this in preparation for my first solo trip across country with my 14-month-old son. And wow, am I ever glad that I did! It worked perfectly with my 22-inch rolling bag and (rather heavy) Diono Radian car seat. My son enjoyed riding in it, and I received many comments/complements from flight attendants, pilots, and fellow passengers about how cool and smart it was. I practiced with it a couple of times at home before we left, and by the time we we're at the airport, it was a breeze to undo and reattach at security.One caveat, though. I did have to use a different roller bag than I'd planned on, because I found that the weight of the carseat when attached kind of threw off the allignment of the bag with multidirectional spinner wheelsi. Howver, it worked perfectly with the fixed-wheeled bag.Honestly, if you travel like I do, with multiple carry-ons and a big, squirmy toddler, this will be the best 15 bucks you ever spend!
