I bought it a couple of years ago and I think it's a great way to attach your carseat to the carry-on. When Martie was 3 I didn't bring a stroller and it was ok to push her in the carseat attached, but it was easier if she walked with me and then I strapped her carry on back pack in the carseat and walk with her her. If you have a little one you might want to go with a Gogo kids, but for a toddler who needs a seat, this works really well.
