Dual action vibrators offer simultaneous clitoral stimulation and vaginal penetration. The shaft may or may not have beads, and a second piece curves out near the base and hugs the body, providing clitoral stimulation. Some toys will have a third piece designed to stimulate the perineum and anus.
The best known dual action vibrators are the Pearl Rabbit and Rabbit Habit, made famous by Sex in the City, and now commonly referred to in magazines and television programs.
These toys have a strong and loyal following, but they aren’t for everyone as they are only for penetration and therefore are not as versatile as a straight vibrator. They do one thing, but they do it well. Dual action vibrators are available in jelly rubber, silicone, or more recently elastomers. Many dual action vibrators are high quality and are made with Japanese motors, but there are even more knock offs which are inexpensive, of poor quality, and tend to break easily.
