あ wand vibrator is a massaging device which is often also used as a vibrator and a sex toy. It consists of a rounded vibrating ball attached to a handle. The vibration is provided by an electric motor in the handle that rotates an unbalanced flywheel mounted either within the vibrating ball connected to the motor via a flexible coupling.
It was originally manufactured for relieving tension and relaxing sore muscles, however, it is most known for its use as a sex toy. Sex educator Betty Dodson popularized its use as a vibrator and masturbation aid for women during the sex-positive movement in the late 1960s. It functions effectively as a clitoral vibrator, to bring women to orgasm.
