This toothbrush is not ultra soft, the bristles feel more rougher than a normal soft toothbrush's bristles. For comparison of a true ultra soft toothbrush first try out Colgate's ultra soft toothbrush with the ultra slim tips. When comparing these two toothbrushes, the bamboo toothbrush does not compare to the Colgate toothbrush. The head of the bamboo toothbrush feels very thick, and it is more difficult to maneuver in your mouth than regular toothbrushes. I liked the concept of it being made out of bamboo because everyone has to replace them about 3 months, and plastic lasts forever. Regardless of it being eco friendly, they also have to be comfortable to the user.
