C-rings (the C stands for constriction, not cock) can be fairly hit or miss. The first thing I want to stres about rings is that it is important to apply lubricant before placing this toy on yourself or your partner, as it can pinch the skin or pull hair, putting a damper on the fun. This should be put on after an erection is achieved. One band goes around the shaft and the other goes around the testicles. The band that goes around the shaft can cause the penis to swell slightly and make it appear larger, so if you are trying to talk your guy into trying it, just tell him that! What guy does not want to try a toy that makes him look bigger, right? The band that goes around his testicles applies gentle pressure.

Here are the pros of this product:
It can make yourself/your partner look and feel larger. The bands slightly reduce blood flow and can make you/your partner last longer, but they are still able to achieve orgasm. Some men report that the orgasm is even more powerful than normal when using a c-ring. The silver bullet that is in the top of the c-ring causes vibration that can be felt by both partners, adding a fun sensation to intercourse. The nubbies surrounding the bullet are designed to stimulate a woman's clitoral area in order to increase her pleasure.

The bad:
The issue I found with the clitoral stimulation aspect is that you really have to be positioned properly to achieve clitoral contact, and even then it does not always hit the right area. Another downside is that you cannot choose speeds or functions. It is also a pain to remove during intercourse, should you or your partner decide not to use it anymore. It is also not particularly powerful, though that should be expected from something that runs on watch batteries. At times it can be difficult to feel the vibration at all. For the price, I am not sure it is quite worth it.

Side note:
This toy may be good for added sensation during fellatio or manual stimulation.
