Charged BigO is equipped with a rechargeable 3-speed motor. This thick and stretchy cock ring with a vibrating motor simultaneously provides erection enhancement and clitoral stimulation. The stretchy and thick ring on the BigO fits comfortably around the shaft. Its powerful compact motor is quieter than regular vibrators but the deep satisfying vibrations arent sacrificed. On a single charge, the BigO will run for 60 plus minutes. Made of body-safe SEBS and ABS plastic. Phthalate and latex free.
