We just bought the seat for an in-state trip with the hope to be able to use it abroad as well this year. It is very easy to use, super lightweight, and appears to be quite comfortable. We haven't taken longer drives than 45 mins with it yet, but the kiddo did fall asleep in it once (seemed to be comfortable enough for a nap). This is so much easier than lugging around large car seats and/or bases. We didn't purchase the travel bag, just threw it on the handle of our rolling carry-on luggage and it was totally fine. Fits into overhead bins and below airplane seats so you can put it in either position as carry-on. So far, it seems to be worth the money.
