Review (1/5): Bad batch
This was my second purchase from this brand. While I was happy with my first order, this one leaves me unsatisfied. Bristles turned into a very rigid brush that ended up hurting gums and even caused a minor bleeding. I'm not an aggressive brusher. The brush looks like a lump only after 4-5 days of use. While I'm not going back to plastic toothbrushes, I will turn to another brand of bamboo brushes.
