Perfect Toothbrush
This is the third bamboo brush I've tried and easily the best.  I did have some trouble with loose bristles on one of them, but after a few days removing them as they came loose (maybe 1 per day), it settled down and lasted longer than I expected.  The bristles are firm enough to work but soft on the gums so you will use it as intended.  This is my new go-to toothbrush.
