Query: Clean Machine!

I have always wanted an electric toothbrush but didn't want to blow all that money on something I could do myself with a $2 toothbrush. I WISH I HADN'T WAITED! You never knew your teeth could feel so clean! I know that sounds strange but it's true! My gums are healthier, my breath fresher, and my teeth whiter! This toothbrush is comfortable, easy to use and easy to travel with. Don't wait any longer...make the investment and see what a difference a little technology makes!
