4Us cock ring by Rocks Off Ltd. - review by Boobs and Lubes

Add resource

Lord of the Rings; Rock hard vibrating erections for your queen.

This is truly the lord of the rings(so far), quality construction, good design. We will get regular use of this great sexual accessory.
Great product, worth the price and will replace any other vibrating cock rings you may own.
Could be a tad bit stronger, adjustable and seamless.
Rating by reviewer:
extremely useful review


For the uninitiated; a cock ring is used to preserve or enhance an erection, and can be worn around the base of your cock or around the base and balls.

We have had a long and diverse love affair with cock rings, we have had the basic rubber "O" ring, the elastic with adjusting button, the simple leather(with Velcro enclosure) the durex disposable one timers, the jelly type that accommodates and egg/bullet vibrator. These experiences have allowed us to know what we want in a cock ring, but more importantly it's allowed us to know what we DO want. The above mentioned sex accessories are all fun, but each has a major flaw or do not vibrate. Our ideal cock ring is one that;does not bind/pinch(see O ring, leather adjustable and elastic w adjusting button), stays in place(see jelly with insert) and is positioned well to stimulate her clit(see disposable durex, etc.) The 4Us cock ring delivers on ALL of these fronts.

When we first recieved the cock ring we liked the texture and materiel which turns out to be a proprietary materiel called Intramed. The following comes from the manufacturer;

"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. "

The materiel is smooth and soft but has a density that the Mrs. liked and a elasticity that nicely accommodated the Dr.(me LOL). There was a slight seam that did not feel irritating to the fingers and later did not affect the performance. The packing was a simple hexagon clear plastic box, it was easy to remove and could be reused for storage(we chose not to use it).

    • Mutual stimulation

Material / Texture

The Intramed is a nice feeling well textured materiel and that flexes well. Its also durable and easily maintained with soap and water. The materiel transmits vibrations well. Our bullet did not have any seams, just the harness(again, it did not affect usage).
    • Light odor
    • Stretchy

Shape / Design / Size / Fit

The 4Us is 5 3/4" long and is big enough to reach the Ms.'s clit, it seems to contact her better if were close together. We chose to wear it with the bullet side up, it could be used the other way to stimulate her ass(more testing is needed,LOL). The opening is able to accommodate a 2 1/4" cock and we were actually able to get it around her largest dildo(The Jumbo Jack Man-o-war). The little thinner U at the bottom of the loop is critical in giving it the expansion we needed. Both the man of war and myself just barely fit in. If you like to wear the your cock ring over the cock and balls, this will NOT accommodate that.
    • Fitted - must measure before purchase
    • Only fits on penis shaft

Functions / Performance / Controls

The 4Us is powered by one N battery and has one speed only, I'm curious when the toy makers will break down and make adjustable bullets, I have yet to see one. This toy could benefit from stronger vibrations, and adjust-ability is always welcome.
    • Comfortable during use

Care and Maintenance

Soap and water plus a 10% bleach solution, after the bullet is easily removed. Very easy.
    • Easy to clean


Hexagon plastic box, easy to remove. No instructions printed on the box.


We love our 4Us cock ring, its well built in our opinion(the seam didn't affect us). It transmits the vibration through my cock and we both get both internal and external stimulation. It's a good size for us, but if your on the skinnier side you may want to look elsewhere, it can stretch but it cant shrink.

He says; For me (Dr.) it was very comfortable and it provided that fullness that I enjoy with my favorite standard leather adjustable. This works for intercourse and I found masturbation to feel great as well.

She says; I love it when he wears a cock ring, this one felt great for the thickness it gave him and the vibration we both enjoyed. I was also able to use it with my favorite giant dildo( a big plus).
Follow-up commentary
We like the idea, but it just doesn't compare to my button up strap. It's just too bulky and hard to keep on her clit.
