Two women are suing Apple in a class action suit alleging the tech giant's AirTags are "unreasonably dangerous" products that can be used by stalkers. The women say they're suing on behalf of all those who were tracked by AirTags without consent. The suit was filed Monday in San Francisco federal court. AirTags are battery-powered devices about the size of a quarter, designed to be used to keep track of your keys, purse, backpack, and other belongings. Apple brought them out last year.
