Carrier sold his invention to Wham-O where they replaced Naugahyde with plastic to reduce production costs.[4] Beyond 2001, Wham-O and makers of similar competitive products later included various enhancements such as an inflatable pool at one end of the sliding surface, spray tubes on both sides and longer paths.[5][4] The Consumer Product Safety Commission (CPSC) and the manufacturer recommend that the use of the toy is only for children to avoid back and neck injuries when it is used by adults and teenagers.People older than children might stop suddenly when diving onto the toy due to their weight or height.[6][4] In 1993, CPSC provided a recall notice along with Kransco, which owned Wham-O at the time, to warn users of the dangers; the product was not taken off the market completely but was recommended only for children.
