This is a cock ring - so it's obviously used to prolong/improve erection thus improving sex for both partners. The 4Us Cock Ring did exactly that... and more! I'm almost tempted to throw out all of our other favorite cock rings after using this one. I think advanced users would appreciate this more, only because it vibrates pretty darn powerfully and it may bother someone who isn't used to that.

A cock ring can be worn in several ways:

- Right underneath the head of the penis
- Around the balls/scrotum
- Around the base of the cock
- Around cock and balls

However, this one works best used at the base of the cock or around the cock and scrotum. Using it underneath the head of the penis would only cause discomfort since it's a little roomy.

On the product page and in the users guide it shows you the two best ways to position the ring. One position adds more vibration to the cock and balls, while the other is worn upright so that the vibrating end stimulates the females clitoris.

This cock ring appears and feels to be made of silicone - but it is not. It is actually made out of something called Intramed.

Safety:
8

Components:
Specially Formulated Thermoplastic

Properties:
Rocks Off have developed their own medical grade material called IntraMed. IntraMed offers similar benefits as silicone such as but is fully reprocess-able and recyclable making it an environmentally friendly alternative and ideal for certain types of toy. It is non-porous, odorless and phthalate free. This material has been tested to the highest standard and are CE and ROHS certified.

Care:
Can be used with all lubricants except oil and can be washed with warm water and antibacterial soap or 10% bleach solution.

There is very little texture to this ring aside from the bumps along the inside. This was something my partner really enjoyed, as it wasn't overwhelming but the bumps were still easily felt. The material itself feels exactly like silicone.

This ring fit exceptionally well. It was snug, but not too snug, around my husband's cock (he's quite thick and it's always hard to find a fit). His erections lasted longer and he was much much harder! This ring works as well as one made of steel.

The attachment, which consists of the award-winning RO-80mm bullet, is about 4 inches long. It's long enough to reach the clitoris if worn upwards while the female is on top in cowgirl position. If worn downward, this attachment will stimulate the scrotum and cock and even the other partner's outer anal region. A very fun experience!

I can tell you that for most this will easily be a cock and balls ring. It's snug, but the U leaves rooms for scrotum play, depending on the size of your partner. Larger men may have issues with this.

The RO-80mm bullet has 2 settings: On and Off. It is very powerful - about 4 vrooms. So it definitely wont let you down. It's easily activated by pressing a small button on the end of the bullet.

NOTE: The bullet is removable and replaceable if something were to happen to the RO-80mm or if it is too powerful for you.

The RO-80mm is powered by one N (LR1) battery. They are super expensive at stores and hard to find, so I recommend buying them off EdenFantasys.com. You will be happy to know that this cock ring comes with one battery already.

If this thing gets dirty, just wash it down with soapy warm water and dry it off with a cloth. It couldn't get more easier. Just be sure to avoid oil based lubricants, as they will cause the Intramed to become tacky.

You can store this ring just about anywhere. It doesn't really look like something people would expect to be a sex toy, so it's discreet. The box isn't all that discreet, but it makes good storage for this cock ring. You could keep it in a toy pouch, sock, box, etc. Your options are just endless.

This ring comes with a really interesting box, not similar to the Ass-Berries boxes. That is how it's shown online. It isn't totally discreet, as you can see right through the box. So remember that if you have kids, annoying roommates, nosy family, etc. then you want to open your box in the other room.

Rocks-Off Ltd. is pretty big on recycling as far as I can tell and the entire box is made of plastic and a thick cardboard (coated), so it can easily be recycled. It actually has a recycling symbol on the bottom of the package.

There are user instructions, but they are very brief. It all comes in one booklet that seems to mainly be used as a catalog for their other products. The box shows how to put it on (one of two ways, not including use around the scrotum) and it shows how to use the bullet/battery compartment. You can peel these directions off of the back of the box, and I recommend doing so to keep things as discreet as possible.

I definitely had a lot of fun with this cock ring. There's several ways to use it, and room to give to adjust to any position you'd like to use it in, or to adjust to a larger man like my husband. The U adds extra room for use around cock and balls, so it's a very versatile cock ring. Definitely affective!
