Query: LOVED the idea -- but you DON'T need it!!!!

I showed my husband the picture of this item because I thought it looked pretty darn smart. Well, two minutes later he had the carseat attached to the rolling carry on WITHOUT an added purchased strap. You still use the seat hooks from your car seat - both side clips and the top clip. Put the top car seat hook under the top handle of your luggage & the side ones simply around the sides of the luggage. Buy a $0.50 metal ring from a hardware store & clip the car seat hooks to it & tighten all straps. Voila! We tested it with our kiddo in it & she giggled as we wheeled her around the house. Perfect. Now I can easily transport my kid, carry on luggage & the car seat while I travel with her solo. Super easy to detach and reattach while my child is sitting in the seat buckled in (not running around the airport ;) Luggage must be full (duh) and helps if your carry on has larger wheels & a longer handle, mine doesn't but still super easy.
