They would stop selling inexpensive boosters if they weren't safe?! Like they would stop selling cigarettes if they were dangerous? There are plenty of products on the market that aren't necessarily safe or what's best for us! The safest place for anyone is in a five point harness for as long as possible, I wish they had them for adults! I've been in serious accidents including one fatality, I don't take this lightly at all. Smaller children are at risk of sliding under seatbelts, being internally injured or cut by seatbelts, and usually aren't mature enough to keep them on right or not move around while seated, and what happens if they fall asleep in the car? My daughters are in a britax marathon (harnesses to 65lbs) and a britax frontier (harnesses to 85lbs then a booster to 100). Nothing but the safest for me! My oldest was in a marathon in our accident and was fine. Check out weight/height minimums and maximums on all seats, britax's website shows all models and what's best for your individual needs. There are always good deals at albeebaby.com and on new in box items on eBay, babies r us stores let you try the seats out, sometimes in your own car. HTH!
