I needed a set of luggage for my 16 month old that could grow with him and be easy for me to use as carryon when traveling alone with him. This fits the bill and only loses one star because by the photos it looked like the daypack part attached by buckles on sides for fast removal/reattachment but in fact these buckles are extra pointless in the way items and to remove or attach daypack you need to zip or unzip all the way around which takes precious time when you have a toddler. Also this model has a lid type top opening on the daypack not a traditional backpack zipper style which takes getting used to. The backpack straps on the larger part of the bag could use more padding if you needed to haul it a long distance full on you back this is not the right bag for you, the wheels work great though. I even tested it with the Britax carseat and travel strap with my 25 lb kiddo on this bag and it handled the weight.

Roomy and lightweight, sturdy design, will suit my needs regardless of design not quite what I expected.
