I have had a Sonicare Toothbrush for about 8 years and it finally bit the dust . . . so of course, I went out and purchased another one--I love this toothbrush, in fact, whenever I have to use a regular toothbrush, i.e. at the dentist office, I forget how to brush my teeth . . . LOL--this is the best toothbrush and I encourage all of my friends to purchase one for themselves, you cannot get your teeth as clean without it--thank you for a wonderful product!!
