My daughter (7) LOVED this Oral-BÂ® Pro-Health StagesÂ® Disney Princess Power Toothbrush. She has never had a power toothbrush and I was a little worried that she wouldn't like using it. I was way wrong! She loved using her new "Spinny toothbrush"! I din't even have to plead with her to brush her teeth. A few things that I liked about it: - The brush was the right size to fit in her mouth. She has a small mouth and a lot of times the brush heads are way to big and she has a hard time fitting them. This was just right. - The power was perfect. I was worried that the power would be too strong, but it wasn't. It was strong enough to clean her teeth, and even tickle a little, but not so strong that it hurts.
