Safety
I’ll give it 5 stars for safety but it’s very hard to get the baby buckled in because straps are short and can’t be lengthened or let out. My baby is 2 and as she grows I’ll probably have to buy another car seat because of the length of harness straps.

Overall great
Overall, i love this car seat. it’s strong and sturdy. my only complaints are that, if snacks fall in the checkered area, they’re almost impossible to get out. Also, we went on a 7 hour drive with plenty of stops and my 2 year old was complaining her butt hurt. Other than that, it’s great and i know she’s safe!
