Now how does this work?
I suppose if I carefully read the manual that comes with the product, I can figure out how to put it in my mouth so that the two separate heads do what they are supposed to do. In the meantime . . .  I do whatever . . .Maybe some day I will figure out the correct brush position. I have to concur with another reviewer that the head(s) are rather large and using this toothbrush in a small mouth (as mine is) takes some getting used to--and I am accustomed to it after a few weeks of use. I do not like it as well as my Vitality Sonic but my hygienist says the newer models are better. The verdict will be decided, I suppose, with my next visit for my cleaning.
