Bristles Grow Mold Within a Couple of Weeks
I was excited to try these bamboo toothbrushes after reading the reviews.  I tried the first brush & discovered that after abut two weeks there was mold growing in the middle of the toothbrush.  I threw that brush away & attempted to use a second brush, making sure to rinse it after each use with very hot water.  After about another two weeks, the same issue.  I am very disappointed.
