4Us cock ring - vibrating penis ring by Rocks Off Ltd. - review by ana123

Got His Rocks Off

This cock ring can be used for vaginal, clitoral, and anus stimulation. My boyfriend enjoys wearing this for the vibrations when he masturbates. Unlike other cock rings that we have tried, this one does not leave my boyfriend's penis numb. It eliminates the need to press a vibrator to your clitoris throughout sex and end up with those inevitable numb fingers. I am very impressed with this well made toy.
Feel, vibrations, shape
Loud vibrations

extremely useful review


The 4US Cock Ring was the first cock ring that my boyfriend and I ever experimented with. We bought it in an effort to make me orgasm easier and quicker. Sometimes holding a vibrator to your clit through the majority of sex can be frustrating, especially when your fingers go numb from holding a tiny bullet. This vibrating cock ring would be ideal for men who enjoy vibrations as well as the pressure of a cock ring around the base of their shaft and for women who need more than just penetration in order to have an orgasm. Because it is waterproof, this cock ring is perfect for sex in the shower.

Material / Texture

The 4US Cock Ring is made out of silicone, a material that I prefer over plastic because it is smooth to the touch. The silicone smell is unnoticeable to me therefore my boyfriend can wear this cock ring while I give him a blow job. The ring for the penis is firm but not rigid. It can bend. The bullet is your typical bullet. However, the entire product isn't silver. The tip is silver and the rest of the bullet is black.
    • No odor
    • Not porous at all
    • Stretchy

Shape / Design / Size / Fit

The ring of the 4US cock ring had a thinner loop, making it easier to accommodate larger girths. It is easy enough to stretch over the penis and did not cut off the circulation in my boyfriend's penis. He is of average girth. The nodules on the inside of the ring provide added stimulation for the guy, a feeling my boyfriend enjoyed. The bullet is contained inside of a sleeve on the top of the cock ring. This sleeve has ridges inside that hold the bullet in tightly. To get the bullet out, I had to twist forcefully several times. I found that the location of the bullet was good for clitoral stimulation if in the right sex position.
    • Will fit most men

Functions / Performance / Controls

The vibrator that this cock ring contains is the award winning RO-80mm bullet vibe. The vibrations are moderately strong and if held in place, I was able to achieve orgasm. However, the silicone sleeve does stifle some of the vibrations. The bullet is easily turned on by simply pushing the black button on the top of the bullet. It is a one speed bullet. One push will turn it on and another push will turn it off. Because of the location of the on/off button, we did not have problems with the bullet accidentally turning off during sex. This bullet uses a 1.5v N/LR1 battery. This bullet is not quiet and does give off a distinct buzzing. It reminds me of my mechanical toothbrush except, thank goodness, not as loud. Also, I found that if you screw on the top of the vibrator too tightly, it will not work.
    • Comfortable during use
    • Easy to use

Care and Maintenance

The 4US cock ring should be washed before and after use. It is made of silicone and is therefore non-porous, easy to clean, and able to be disinfected. The bullet however is plastic and can not be disinfected. I use alcohol to wipe it down after a thorough washing in the sink. You can use alcohol, soap, and warm water, or a toy cleaner. I then towel dry the silicone to prevent damage to the material. As usual, I remove the battery in the bullet vibe to prevent damage to the unit and make the battery last longer.
    • Easy to clean
    • Easy to store


The packaging is cute and informative with the slogan “For him to wear and couples to share,” and a picture of the product. Instructions are located on the back of the box. There is a panel next to the instructions that list a few 4US's skills- 100% waterproof, a strong and silent vibrator, made of IntraMed (a silicone material). There is also an illustration showing the proper way to wear the 4US cock ring. More instructions are located on the inside of the lid of the packaging. The bullet comes with the battery already inserted and a isolator disc that prevents the vibrator from working until it is removed.
    • Very informative


We first tried this cock ring in standard missionary position which we quickly concluded was probably not the best position for this product. The vibrator would miss my clit completely and push into my pubic bone. However, the vibrations traveling through his penis provided a pleasurable sensation inside of my vagina. This alone will probably bring a woman to orgasm if she can cum through g-spot stimulation alone, which I can not. We then shifted to girl on top and I found this to be a little better but I was not receiving much clitoral stimulation. In this position however, it is possible to receive anal stimulation by turning the vibrating bit around and positioning it near the anus. Great idea for those who enjoy a bit of anal stimulation. One of the best positions that we tried involved me laying on my back and him kneeling in front of me. If he inserted his penis this way and bent over slightly to meet me, my clit would receive wonderful stimulation and I was free to grind in an upwards motion to increase stimulation. In this position he was also free to press the vibe down hard on my clitoris when I was close to achieving an orgasm. This sent me over the edge every time.

With a little bit of experimentation, it is easy to find many beneficial positions for this cock ring. Also, the orgasm restricting properties of a good cock ring allowed me to achieve orgasm first. I was always left satisfied when using this product.
