I tend to believe that this toy would be most suitable for couples play. Although it does work amazingly well for added stimulation during solo play/masturbation, it is designed to stimulate both partners at the same time. Thhe vibrating bullet is supposed to bump into the woman's clitoris while the male is wearing the flexible ring portion. It is easy to figure out/use, and it doesn't have any real learning curve to it. It is, therefore, suitable for anyone.

This toy is very simple in design. The material used is silicone, and it is very soft and pliable. It is silky/velvety smooth to the touch, so it feels excellent against your body. There are ridges that cover the vibrating portion, as well as little ribs around the inner portion of the cock ring that hug you quite nicely. Also included are two very soft and flexible silicone cock rings in two different sizes.

Overall, I think that the design is very catching. The use of bright colors and high end materials instantly drew me in. It is very easily put on and take off. It is very comfortable to wear, and it will accommodate most average to slightly above average guys. It does sufficiently stimulate the female partner while being used during sex, although it can sometimes can move out of place. It's easy enough to readjust it to get it back to the good spots, though.

The vibration function is very intense and strong. The toy has ten settings that are extremely hard to describe; it almost seems like they change every time you cycle through them. It is controlled by a small pendant type controller with two buttons -- one for power (on/off), and one to cycle through the different vibration patterns/intensities.

I have used this toy solo and with a partner. My partner absolutely loved it; it sent her over the edge multiple times. The vibration function it strong enough that, due to how it's constructed, the vibrating bullet actually jumps around and bounces against the woman's clit. The different vibration settings also seem to change and vary slightly every time you cycle through them.

I will say that this thing drove me absolutely crazy when I used it with my girlfriend. Its vibrations patterns are crazy, and they make it incredibly hard to heard back when coupled with extra stimulation.
