I love this car seat and so does my daughter. As soon as my 2nd child is out of her infant seat we will be purchasing another one. My only complaint is that it is super heavy. It's not a breez to switch back and forth between vehicles. But other than that it's great!
This is the 4th Nautilus we have bought-2 for our vehicles for our 2 & 5 yr old, 2 for the grandparents vehicle. They are great. The only downside is that the crotch buckle is kinda tight in that sensitive area & we already have it let out to the max. Willing to sacrifice that minor detail for the safety & other comforts. Wish I would've bought this seat right after my kids outgrew their newborn seats-would've saved us some money & them some comfort.
