The DUO is a 3 speed, stretchy, reusable dual vibrating ring designed to comfortably fit all sizes. The thicker band constricts blood flow; keeping the blood in the shaft of the penis, the user maintains a firmer and fuller erection during sex. The added pleasure knobs help provide a tighter & more secure fit for him which prevent the ring from sliding or moving, while the pleasure ticklers provide maximum stimulation for both. The 2 high-powered motors each with 3 speeds feature an independent, easy, push button control to facilitate use as needed and customized speed for him and her. The specially designed, thicker vibrating heads are the perfect size to ensure clitoral stimulation for her and testicle stimulation for him.
