Review (4/5): Bristle Isn't Very Soft But No Issue with Mold
I did not have any issues with mold since I took care to dry out the toothbrush. The bristle isn't very soft and the wooden handle + design resulted in chafing the inside of my mouth when I first started using it so my mouth kept bleeding :( I learned to brush more gently as a result which is a good thing, I suppose. Another complaint I have is how easily the bristle becomes misshapen--I only used it for about a month or less and I already have to replace it with a new toothbrush. I don't think that's acceptable given the price. Aside from these issues, it is a decent product.
