My favorite quality for this device has got to be the dual bullets. If used correctly, it can send shivers throughout your body. It has no taste or smell and is super stretchy to fit almost any man's girth. It is also very easy to clean. Just a little soap and water will do the trick. The bullets are fairly quiet for those spontaneous nights when the kids are home or the in-laws are in town. It is also small and discreet, so you can pretty much take it anywhere. I enjoy using a vibrating anal plug in conjunction with the dual vibrating cock ring. All the vibrations combined together help to give you an orgasmic experience.
