Pros: Bristles vary in stiffness, ergonomic handle, handles moisture well.
Cons: At very high temperatures some bristle falls out
The bamboo toothbrush has a clean design, does not absorb water or warp when wet for a long time. The bristles stay intact until you put it in hot water for a long time. It seems like the tip of the brush has harder bristles so you reach the back teeth better. I was worried that after a while the handle would have a strange odor, but it does not happen.
