For the money you give, it's okay. The white ones that are visible in the photo between the wheels came off on their own as soon as we put the baby in (we have removed them, but maybe we have made some wrong use and that's why they came off). The red ones that appear as buttons are decorative, and when you press the helicopter, it makes sounds, but it doesn't stay attached to the stroller, resulting in damages after some "flights" on the floor (the plastic covering the lights broke).
Finally, the fabric at the point where the baby "sits" is held on the plastic when you put it on, and it is a bit risky for it to come out of its place or tear (it happened to us).
I consider the function of the cradle unnecessary and it doesn't do anything special.
I suggest some other option if you want something more than the basics. If not, it's okay for its price.
