We offered these suitcases to our grandchildren, twins 2 years and a half and the youngest 15 months. The children were happy to do as adults, even the chip that does everything as his cousins. Suitcases are super strong, we had some fear for the chip, but no problem, it only goes up and down without assistance and to race, it is not the last. Do not hesitate, if you need to invest in a suitcase, you take the car, train or plane (it passes in the cabin), your kids will love it and it helps to take them, they can romp in or if waiting to relieve you if you need to wear them, they go over, they push or pull you, you can even hook them to form a train, in this case, if you want to go unnoticed, it is Damn, that's crazy laughter guaranteed. Only one default, it must be one, they are a bit expensive, but we do not regret it, the children are really fun with, while driving but also during our stay.
