Once assembled, the Spinaroo is a great center for the kid or in reality the kid is the center of it all. The seat with the wheels makes it very convenient to move the baby around, so the baby can give his/her attention to all the toys. Most toys have very intuitive rotary, scroll, slide motions that you dont have to teach your child to perform. Put them in there and you will be surprised to find them on their own.
The height is adjustable.
I have Cheerleadered my baby to pull the string on another toy that produces music. That is a feat.
The feat part with this toy is acquiring batteries that dont seem to be that common. Assembly is sometimes cofusing but that could be me trying to touch the nose, going around the head.
