I wanted to make something for my 1st baby.. and this was perfect. I made fishes with felt and hanged them to this item.. the mobile is sturdy when it clings to the crib.. the plastic might look less strong but it is good quality considering my baby's safety in the crib. The mobile is also easy to assemble. The music is soothing but needs manual keying to run it and make the mobile go round.. I wish they had the option of making the mobile move in circles using an app..
