The seat is great and easy to install. But the owners Manuel is awful. It’s not in order for what you need to know, not clear on what to do based on your child’s weight, and unclear on how the seat functions. After installing I had to adjust the belt buckle, but could not get it off (turns out it has to be in recline to turn back to the white arrow and remove), and searched for several pages on how to move the buckle, and still unsure if it’s safe in the middle position based on weight/size. And the latches aren’t included in the main install- but should be used is baby is under 30 lbs. ?
