I just wanted to tell those of you who are interested in a Phillips Sonicare, Amazon has the Essence toothbrush for $34.95 and 6 replacement heads are $53.13. This is an older model. It is the one that I use and I love it. You should know that when you use it, you should unscrew the top and rinse it out. I had the opportunity to get the expensive new model when I bought this, but I didn't like some of the reviews on the newer one. Even though I have a small mouth, I prefer the larger brush because I feel it covers more area and is therfore more thorough. Also, the battery life of the Essence is very good in my experience. I bought mine and my husband's about 5 years ago and they both perform just like new. And like I stated in an earlier post, I've owned a Sonicare for 22 years now and I just cannot say enough positive things about them.
