Norelco Rotary Shaver
Neither foil nor rotary shavers can shave quite as close as manual razors. (See our report on razors for reviews of manual models.) While the noise of electric shavers annoys some men and could be another reason to opt for a manual razor, rotary shavers overall seem to be quieter than foil models.
In the end, experts say there's no single, definitive way to determine which type of electric shaver is best for you. Some reviews suggest that rotary shavers work better for men with denser hair and rounder faces, while foil shavers are better suited for men with lighter hair and thin faces. But ultimately, the decision boils down to personal preference.
