This was a perfect solution for us when we were faced with buying another car seat after having a second child. I didn't want to buy more car seats just to buy booster seats later on. My 2 year old is tall and fits fine in it using the 5 point harness. Also we haven't had any problems and have been using it about 3 months now. My husband installed it in his Honda Pilot and it fit fine. He had one little glitch installing it, but it was something he did wrong and ended up figuring it out. We liked it so much we just bought our second frontier for our other car.

This is by far the best car seat ever I have 10 month old daughter and ever since I bought this car seat I don't have any problems putting her in and her fighting me while I put her in she loves it. I would recommend this car seat to everyone. If they came out with this seat when my daughter was born I wouldn't have gotten a travel system. It's worth the money especially the fact that it goes from an infant to a booster seat.
