OK, but the notes chosen are annoying!
I bought this for my son who is still a little too young for this (He'll be 5 months this week). When looking for entertainment, I grab it sometimes and play a few little songs on it for him. He likes to listen sometimes. So far he only spins the spinners with his feet and not his hands (how he figured that out I don't know!).

The thing that kills me on this and the reason I only gave it 2 stars is that whoever designed this must not have been a musical person. I am a music teacher so this is really irritating to hear--the notes from left to right on the toy are F, G, A, B, C. The B should be a B-flat for a proper scale. When you play the notes in order the B natural (yellow) just sounds terrible b/c it does not belong in that scale. My friends are joking and probably rightly so that my son is going to grow up with a funky musical scale in his head and think it's correct. I think the only things I could play on this were Hot Cross Buns, Mary Had a Little Lamb and the theme from Dvorak's New World Symphony. If they had made that a B-flat instead of B natural then we'd have endless possibilities!

My daughter likes the ball better
We got my daugher this and the rainforest chime ball and she seems more interested in the ball - she likes this but only for about 2 or 3 minutes then she is bored

My son wasn't interested
It's very awkward for the child to play with, they can't really hold on to it. and it doesn't sit up right only flat on the ground. Hard for him to fully reach everything and then it scoots because he can't hold to it.

Cute
My son just learned to play with this toy and he loves it during tummy time. My son is 3 months old and will play it with one of his hands during tummy time, it keeps him entertained for a while, making his tummy time last longer!

Don't waste money
Im not sure why so many people liked this.
I bought it early on for my baby. She's now 7 months and I brought it out again. She she spun the wheels but its sooooo quiet & you need to spin so fast in order to get the slightest noise. As someone else mentioned the notes all practically sound the same as well.

My daughter likes to bang things anyway, not spin.
