This is a dual bullet vibrating cock ring intended to give both partners stimulation while having intercourse.
One bullet is located on the top of the ring for her pleasure, the other is located underneath to stimulate him.

This ring is good for couples', and even for male solo play if he so desires. The cock ring can be worn during foreplay, and also during sex. It is not hard to use, and can be worn by beginners, and advanced users as well.

The ring can be placed on a dildo as well, for her added pleasure.

I believe the best way to use this cock ring is during intercourse, for added tingling sensations for both partners.

The Big O cock ring is made with TPR silicone material. This is material is able to stretch, so this will fit most men. The max that this ring will stretch is up to 3 inches. TPR silicone is sticky to the touch, and is a big lint/hair collector; this being said I would highly recommend that the male be shaved, as the material will catch, and pull any hair that it comes in contact with.

The ring has little nubs, with add to the texture of the material. The nubs could be felt during sexual intercourse.

There is no smell to the ring, even fresh out of the package.

Silicone is a non-porous material, for those that like to share their toys.

I like the design of this ring, having the dual bullets, that provide stimulation for both partners; is a bonus for me. The vibrations are pretty strong for such little bullets.

The material is tricky to place on the penis, it is a tight fit, and will grab the skin, and hair. I would recommend using a water- based lube; to help ease the ring into place.

My husband did not care to wear the ring, not that it was uncomfortable to wear, he felt like the ring was more of a distraction for him. I on the other hand enjoyed having the added vibrations, and texture.

The ring was easy to remove, as long as there is some lube. I again would recommend placing some added lube before trying to remove the ring.

The Big 0 ring, is pretty strong for a disposable ring. It provides stimulation for both partners, without costing an arm, and a leg, making it much easier on one's wallet when you toss it away.

The bullets run off 2 watch batteries, which are included in the package. Each bullet has a push button for easy access to turn them on, and off. I was impressed by the strength of the vibrations from such a little bullet.

I liked the vibrations while having sexual intercourse, to me they added to the pleasure, by giving me added stimulation. My husband on the other hand did not care for the ring at all. He said the ring distracted him, and he was more concerned with making sure the ring was in place, and how it was performing.

Silicone material should be cleaned before, and after each use with warm water and anti-bacterial soap. After the ring has air dried, I would recommend storing this ring in a plastic bag; to keep lint, and hair off the ring.

Silicone material toys should also be stored away from other material toys, as it does not play well with other material.

Since this ring is a disposable ring, it will only last a few times, before it will need to be tossed away.

The ring comes in a blister pack. The ring is clearly able to be seen, so it is not discreet at all. The packaging has information on the front, and back of the packaging.

I think for for a disposable ring, it works pretty well; just do not expect it too last more than a few times.

I placed this ring on my dildo, and I found the added vibrations a bonus. The bullet was able to stimulate my clit, while the dildo was inside of me. I found it to be pleasurable, and would invest in another vibrating cock ring.

We also used this ring during sexual intercourse. My husband is shaved which I highly recommend; so the ring does not pull the hair. I placed some water-based lube onto him before placing the ring. The ring fit him fine, and was tight to his skin.

Before removing the ring, we placed some more lube onto him, and the ring slid right off.

The ring only lasted me 2 times, before it fell apart. The bullets still worked fine, but the ring itself tore apart.
