Fun Factory took Miss Bi''s two powerful, rumbling motors and put them into a design that''s long and firm, for size lovers who crave dual stimulation. The Lady Bi is flexible-but-not-too-flexible, so users can enjoy a more intense pressure without sacrificing the comfort of a shaft that adapts to motion. The length provides more options for play, whether that means vibrating the arousal-triggering a-spot or simply having greater mobility. Six vibration intensities and six vibration rhythms give diverse pleasures.Adding to the elegant design, Lady Bi''s loop handle makes switching positions easy. The intuitive raised button controls come with a quick on/off function and a travel lock.
