But even though I feel confident in my flossing routine, there's always room for improvement. So when Instagram hit me with a targeted ad for Flaus, a smart electric flosser, I was instantly intrigued. The Flaus Electric Flosser Starter Kit ($119, originally $130) comes with everything you need to get set up: the flosser, charging base, charging cord, and recyclable floss heads. In person, Flaus looks like an electric toothbrush, but with a floss head instead of a brush head. Although Flaus says they move the floss head in a left-to-right motion, I didn't notice any real side-to-side action as much as a general fast, fluttery vibration.
