Electric shavers remove facial hair to provide a smooth, clean appearance, while electric trimmers are tools to cut body hair to a shorter length. In addition, electric trimmers generally come with attachments to trim ear and nose hair.
Replacing traditional razors, electric shavers are available in wet and dry models that give the user the ability to shave in either environment. Furthermore, electric shavers remove the possibility of nicks and cuts that are commonplace with traditional non-electric razors.
Alternatively, electric trimmers enable users to shape beards and mustaches while they remove unwanted hair on the back of necks, chests, arms and legs.
