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.

Healthy toothpaste

Hard to see a difference so far
Style: Wild Mint 2 Pack
Using for 3 weeks and doesn't foam up or increase with brushing like regular toothpaste does. Effects are minimal thus far.
