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!

Good quality toothbrush. However..
Color: Pink+purple
Got this for our 3-year-old granddaughter who needs to keep her teeth clean. Problem is, it tickles her teeth so is not used to the extended should be. Don't know how to solve that issue, but it is a good toothbrush.

Kids Toothbrush
Color: Red+blue
Purchased this toothbrush for my 5yr old! He loves it especially because it comes in his favorite colors. The prices is great as well! The charge lasts forever. I have only charged it once since I purchased. I purchased it for travel through Europe so I could throw out the toothbrush heads. The customer service is 10/10. Reached out regarding replacement brush heads because I know my son will throw a fit if they aren’t the same ones and told us they will be available for purchase and sending us some in the meantime. So now I will also be purchasing the matching water flosser!
