Turn the lights down low and boogie on down with the Big O Glow! The Big O Glow is a one-act stage show and a revelation in vibrating rings. Place the Big O Glow on the man with the vibrator and light facing out, push once for a steady mode vibrating and a steady red light that literally will light up the room. Push twice into the 9 stage pulsing mode and let the stage show begin as the light flashes with the pulses.
