These tracks have added a lot of fun to my son’s bath playtime. He hasn’t figured out how to put them together yet because he’s not even 2. However, his dad and I have had fun making new tracks for him to send the little ducks and balls on a fun ride! These bath toys add a great distraction from the mundane bath-time routine. They are easy to attach together and adhere well to the shower insert walls with the suction cups provided. We loved it so much we bought a second set to build a longer track. We figure he will really enjoy it as he gets older and learns how to put them together and design his own own tracks. Would definitely recommend. Best for kids who are no longer putting things in their mouth as the little pieces would definitely be a choking hazard. Would easily provide entertainment for kids as old as 8-9.
