Men's electric shavers come with either foil or rotary cutting blades. Each type of electric shaver has its devotees. We haven't tested any women's models lately because they've consistently performed relatively poorly in our tests. But then, there's no reason women can't use a men's shaver.
Electric shavers aren't cheap. Expect to pay at least $60 for most models and $150 or more for some. They're also expensive to maintain. You'll need to replace the head every six months to two years, at about $25 to $45 each. And once the rechargeable battery no longer holds a charge, replacing the entire shaver is often less expensive and easier than replacing the battery.
