Realistic Vibrators are more like dildos except that it vibrates. It's a major turn on for many people because it tries to mimic the male genitalia, they call it "phallic shape" or shape of a penis. Not only it manifests the shape but the texture, size and color as well. Materials like silicone, futorotic, jelly, cyberskins and UR3 materials make it close to the real thing. With veiny textures, a penis head and usually beige in color, realistic vibrators are close and some say it's better than the real thing.
