These kept kids (ages 1-4) and adults entertained on plane rides! They make a great sound which was an added bonus for the baby. The one drawback is they do not hold up to chewing (not surprising but good to know if you're buying for little ones) and are fairly easily squished side to side so they don't collapse lengthwise anymore. For the price I'd definitely buy again, they lasted for our whole trip, but not a forever toy.
