Nuna AACE: Belt-positioning booster convertible between high-back and backless mode — the two modes have genuinely different weight floors and minimum ages (high-back: 40 lb / 4y+; backless: 50 lb / 5y+), same height range for both. Do not use if more than 10 years old (printed number, per manual).
That is the record of the brand — not a verdict on these models. A recall names specific models and manufacture-date ranges, and a seat missing from the record is not "recall-free": check nhtsa.gov/recalls with the model and date of manufacture on your seat's label.

Which is right for my car and child, the Graco TurboBooster LX or the Nuna AACE? That depends on your specific vehicle and child — this page compares published manufacturer specs only, not fit or safety. Check the seat manual, your vehicle manual, NHTSA's car-seat finder and ideally a certified CPST before deciding.
