To use the Screaming O DoubleO 6 Vibrating Ring, first make sure the AG13 batteries are properly installed. Then stretch one ring around the shaft and the other around the testicles for a snug fit. Turn it on and enjoy the enhanced pleasure. When you're done, simply remove the rings. Keep in mind that this product is made of SEBS silicone, so avoid using it with silicone - based lubricants as it may damage the material. To maintain it, wash it with mild soap and warm water after each use, and dry it thoroughly before storing. Make sure to replace the AG13 batteries when they start to run out to keep the ring functioning well.
