The mighty marble - cock ring by Evolved Novelties - review by ToyTimeTim

Add resource

Lovin' the idea...while it lasted.

From Evolved Novelties comes the Mighty Marble, a cock ring for those times when a vibrating cock is wanted or when the pleasure of an engorged cock is what your partner craves. They have created a ring that puts the multifunction vibe directly on the shaft, or you can place the vibe in line with the penis so the vibes can be directed to your partner. As if that wasn't enough, they even include a sleeve that hangs off the ring, which houses a removable metal ball for even more stimulation.
Positions for two vibes, 7 settings, nice fit.
Thin areas may tear, second vibe is not included.

extremely useful review


Guys, let’s face it, a bigger cock and prolonging ejaculation is something we all crave and dream of. Good thing some guy back a couple thousand years ago decided to put a ring on his cock to pave the way for all of us, eh?

Fast forward to present day and we find the Mighty Marble, part of the Zero Tolerance line from Evolved Novelties. This vibrating cock ring gives you ease of use and multiple uses/positions all in a stretchy material for a great fit and simple care.

Once you decide where to put the vibe you only have to apply some lube to the ring and penis, slip or stretch the ring into position and turn on the vibe. Sounds easy enough, right? Well, there are many possible ways to use this ring so deciding the configuration may take some time.

Material / Texture

You get three materials with this ring, they are TPR, ABS plastic and Metal. First, the ring is made from body safe TPR. This gives the ring a good amount of restriction without being uncomfortable, while a very slight chemical taste/smell will not distract your focus on the task at hand. The vibe is made of hard ABS plastic, great for transmitting vibes and cleaning ease. Lastly, the 1/2" diameter ball is made of steel with a chrome like finish.

The TPR does have some drag on dry skin, so use of a good lube will go along way for comfort. While the material is not sticky, you still may want to trim pubic hair a bit - a pulled hair or two is not always wanted.
    • Rigid
    • Somewhat porous
    • Stretchy

Shape / Design / Size / Fit

The ring is about half an inch thick and wide. The ring has nine domes front and back surrounding the penis with a nubby covered, tear drop shaped extension that houses the metal ball. There are two holes: one opposite the extension for clitoral, testicle or anal stimulation, and one at the base of the extension but passing through two parts of the ring so that the vibe rests across the penis, turning your cock into a real live vibrator.

The inside diameter starts at 3/4" and will stretch to 1 3/4" with ease. Larger diameters can be achieved with care, but the area at the bottom might tear ruining the ring. This makes it a shaft only ring for most, but some may be able to use this ring around the "whole package" for even more stimulation/options.

The extension protrudes 1 3/8" from the top of the ring. With the ball furthest away from the ring it will flop around during use some and is a nice addition when things are hot and fast, but it is unnoticeable during slow passionate times. A bit more length would have been helpful here. A nice design feature is that you can move the ball inside the sleeve from the base of the ring to the very end; this should help reach most clits out there. Furthermore, this sleeve could also be used to house a bullet vibe. I could not get the included vibe in: the material became very thin so I did not tempt fate, but I had a smaller corded bullet vibe that fit and worked great.

Follow safe cock ring guidelines and do not wear more than 30 minutes without a couple of hours in between and remove if any pain or discomfort is felt.

    • Will fit most men

Functions / Performance / Controls

To take this cock ring closer to erotic bliss, Evolved thought to include a seven function bullet vibe to keep things interesting. To turn the vibe on you have a simple push button at one end of the bullet. Press and hold the button to start the vibes, and quickly press to cycle through the settings. Press and hold to turn off. You get three steady vibes: low, medium and high. You also get 4 patterns: a pulse, an escalating, a pulse pattern that switches from low to high vibes and a fast, high pulse. The vibe runs on three LR44 batteries and lasts for two or three sessions (about 45-55 minutes) on the high settings.

The vibe fits easily into the ring with just a dab of lube, although you may find that no lube is the way to go. When the vibe is in position for partner pleasure, it's great that you can adjust the bullet farther out or closer in depending on position. Across the penis not only puts the vibe in direct contact with the penis, but applies pressure so that the vibes transfer and can be felt by your partner. Have a couple extra bullet vibes? Add them in the other hole and extension and turn your ordinary cock into a jack hammer...look out Magic Wand!

I recommend that the ring be put on before erection when using the bullet across the penis. When stretching the ring over an erect penis, the bullet tends to fall out of one side of the ring. You can still get it put together while it is on but that's kind of a mood killer, eh? Just another reason not to use lube on the bullet.
    • Comfortable during use
    • Easy to use

Care and Maintenance

All the materials can be washed in warm water using an antibacterial soap or toy cleaner. The bullet has an O-ring at the battery end and the on/off button seems to keep the water out, so no worries there. One area of caution would be the ball: since it is metal it may rust if left wet, so do not leave it in the ring if lube was used and dry off after cleaning.

You can store your ring in the original package or a zip top bag. Just be sure keep the ring away from high heat, direct sunlight or dissimilar materials.
    • Easy to clean
    • Easy to store

Personal comments

The big surprise is the seven function vibe, the vibes are moderately strong and the different settings mean we have a choice of intensities.


I loved this ring...all three times I got to use it. While the wife did not care for the bullet poking her she love my vibrating cock. When I added the small bullet to the extension during our second use, she simply could not get enough. I loved the comfy fit: during sex with the wife I only wear rings for the extra stimulation, so long term comfort is a big bonus.

Sad to say that during my third use with the Mighty Marble I pushed the size envelope and the ring tore at the hole at the bottom. I was trying to stretch it over the whole package with the vibe in that hole. Not sure if it tore from the bullet being in there or if that was just the weak link. Either way, guys on the large end or the size spectrum may want to look elsewhere.

We are pretty bummed about the tear as the wife really liked the little ball and the vibrating penis. We will have to give one more a try for sure.

    Thanks for the heads up.

    Thanks SparklyGlitter.

    mpfm, Thanks! Hope you enjoy.

    Jimbo, just a little. (I wish I could have got two bullets like you did) At least we still have the bullet and it fits other rings.

    You're welcome Curiouscat.

    Thanks Booty Bandit.
