Fun new way of flossing.
Color: Blue+red
My 7 year old loves it and it works really well. He’s excited about teeth brushing time again accompanied by water flosser and it can be used in the shower!

Leaks
Color: Blue+red
Water leaks out of the button you press to change out the head so we will be sending back. Other than that it would be perfect, I’m sure it’s just a fluke thing.

Almost Perfect
Color: Pink+purple
EDITED TO ADD: the seller reached out after I left this review and told me the heads are replaceable! Mine didn't come with extra heads and I didn't realize they came off. Thank for reaching out! It looks like the product even comes with replacement heads now and you can also buy them separately. Perfect! These are great. _________ My kids love these toothbrushes and I love that they're rechargeable without needing batteries. However, the charging feature is almost completely negated by the fact that you can't replace the heads! It would be a 5 star if you could swap those out.

Very cute and effective!
Color: Pink+purple, Color: Pink+purple
Very cute and effective brush! I love that there are different settings for different ages and the lowest is soft enough for my 3 year old. She LOVED choosing from the stickers to put on and there’s more left over for when she wants to change them. Stays charged for quite a long time. Would repurchase!
