Summary: It works for what I need it for. Just a Grandma wanting it part of the time. I probably wouldn't buy it for using 100% of the time. Not as sturdy as I would prefer. The shoulder strap has to be put back into the slot every time for it when using it as a booster seat.
Summary: I cannot rate as great, though nice car seat the rigid non-adjustable back would not allow solid installation in our Nissan Versa. When sitting flat on car seat the space behind the back was more than 5 inches and when pulled snug against the back of seat the space was at the bottom.
