My son loves his bottle. He placed all the pieces in the bottle himself. Very easy to create. He uses it as a superhero device during play and when he is sad about something.
Purchased 2 of these amazing bottles, one for my 6 month old daughter and one for my 5 month old neice and they both love them, kept my daughter entertained for a solid 20 minutes! Now my 7 year old wants one too!
