Just Buy it, You won't regret it
I have to say I was very skeptical at first based on the price alone, but after a friend bought one to use on the airplane for her toddler son - and I saw how easy it was to install - I was hooked. I bought one for my daughter and she called it her "airplane" car seat (still does) and we have used this thing dozens of times on planes, in ride shares, in rentals, and even in a shuttle van. The more you use it the easier and faster it is to install. We loved it so much we bought a second one when my son was old enough. I love the convenient and light weight design. It is compact and easy to fold up. I will say my one issue is I do wish it just came with a backpack for carrying because the price is steep. But you can wear the actual seat as a backpack if you dont want to invest in a bag - because it does ironically fit well on your back. We have since purchased two of the Wayb Pico carrying backpacks and don't regret it because there is plenty of extra space for your kiddos blanket and favorite stuffy. I would 100% buy this again and I recommend these to all my travel hungry parent friends.
