not impressed [SEP] there are two reasons for my 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 do not feel i get the same results
