Marketing gimmick - Stick to ProResults heads
I bought this brush, hoping it would perform as stated.  However, when I used it, I didn't any positive effects of the "hydroclean" design.  What I did notice was this:<br /><br />-It was hard to brush my teeth with that annoying rubber thing sticking out<br />-The bristles themselves were firmer than the ProResults brush heads<br />-There were less bristles because of the rubber in the middle<br />-No noticeable "directing of fluids" between my teeth.<br /><br />Think about it:  The only way this would work is if there was a large amount of water rushing between your teeth.  Firstly, when I brush my teeth, I don't have very much fluid in my mouth, only a minimal amount of toothpaste.  Secondly, this brush head is only capable of weakly directing the fluids at your teeth.  If you want the results described by this brush head, buy a Waterpik instead.  As for me, I would rather have bristles cleaning between my teeth.
