The Sonicare Sanitinzing tooth brush.I recieved this toothbrush for a survey. I got to keep it and Iwas so glad that I did!  I have never felt like my teeth were so clean before. I put the toothpaste on turn it on and let the toothbrush do its work! I simply run it over my teeth and it even makes cleaning the back teeth a snap! My son loves to use it and the other feature I like it that the heads are interchangeable! We can all use the same toothbrush with different heads. The tops come with different colored rings that can be asigned to each family member so that you don't accidentaly use someone...
