This Review Title is Not Impressed and the content is: There are two reasons for my 2 star review. First, the brush itself is too firm. It is not at all soft. The ADA recommends brushing with a soft toothbrush. I assume they manufactured it this way to make up for my second reason. Second, the brush head has had the center bristles removed to add the gimmicky rubber channels meant to direct the water/toothpaste between teeth. While I do feel it moving the toothpaste toward my teeth when I brush, I would much rather have bristles in contact with the tooth surface. Afterall, the idea of brushing your teeth is to physically brush away the build up of plaque and tartar. Without the normal number of bristles, I don't feel I get the same results..There are other information for this review, one is This reviewer did purchase it and the other is 24 people think this review is helpful.
