The Sonicare FlexCare and Oral-B Triumph have their fans, but manual toothbrushes do as good a job if used properly. Your first toothbrush probably didn't come with a user's manual. You picked the thing up, put it in your mouth, moved it across your teeth in a vaguely up-and-down fashion, and called it good.
