Cute idea! Very powerful
Style: Dinosaur
I love the concept of it, especially for little ones that like to shove toys in their mouths. But boy is it MESSY, lol. Water will absolutely get everywhere even if you put it on the lowest setting so I just let my kids hold it in the bath. They mostly suck in it so I'm not sure if it's actually flossing their teeth, but that's more of a user error, not a product error. I tried it on myself and it's pretty powerful even for an adult. It definitely functions well. The size is just perfect for an adult, kind of big for a toddler. Overall it's great value for your money in my opinion.
