Turn the lights down low and boogie down with The Big O Glow™! The Big O glow is a one-act stage show and a revolution in vibrating rings. Place the Big O Glow on the man with the vibrator and light facing out push once for 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 pulsing. Time your moves with the sounds and lights and pretty soon the chorus of Screams will soon join in, after all it is a Screaming O. The Screaming O Big O Glow is also waterproof, wireless, has a super stretchy erection band replaceable batteries
