Nuna PIPA RX: Rear-facing-only infant carrier: for children 4–30 lb and 16–30″. Useful life is set by the label on the base/child restraint (no printed number of years in the manual, unlike Nuna's convertible RAVA which prints 10 years).
Clek Liing: Rear-facing-only infant carrier: for children 4–30 lb and 32in or less (printed max-height-only limit, no minimum height printed).
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.
