Super cute!
Comes with two brush sizes. I am not sure how my son will like it as when I showed him he seemed a little scared. He’s pretty sensitive though!  It seems like an awesome brush and like it will get his teeth clean. It may take some time to get used to. I wish the brush insert was thicker at the base. If bitten you can feel the metal part that vibrates. That’s my only critique. Still gets 5 stars! It’s super cute and comes with its own usb charger cord.
