I truly love this csrseat for my toddler. i can't think of one thing I dislike. It has more padding than her infant carrier did, she seems very secure and comfy. I like that it's on a base and you can choose the incline in rear-facing mode. I don't have to worry about head slouching if she falls asleep in the car. The slim fit design leaves extra room in the back for other passengers. The price point is excellent for the quality, in my opinion!
