Sinnovator Tentacle Cock Ring Grinder, front view, platinum-cure silicone cock ring

What our customers say

4.4(16)

Reviewers keep praising the same three things: the textured tentacles work for both partners, the bullet upgrade is a near universal recommendation, and unlike other rings it doesn't shift around mid use. Several mention it made being on top genuinely enjoyable for the first time, and the super soft firmness comes up again and again as the right call. The recurring gripes are firmness choice, with medium running too rigid for grinding, plus one note that the ball ring can slip on some anatomy.

One of you wears it, the other grinds on a patch of tentacles that push back, and suddenly being on top actually does something. If you're eyeing super soft and wondering whether it'll survive actual use, it will, the body safe squish is far sturdier than it looks. And it stays exactly where you put it, because a ring that wanders mid moment is a ring that's failed at its one job.

Size Guide

Full details

Un cockring qui fait aussi grinder, parce que pourquoi se contenter d'un seul job ? Cette merveille à tentacules enlace un partenaire tout en offrant un terrain de jeu texturé à l'autre. Le beurre, l'argent du beurre, et de quoi se frotter dessus.

Pour celui qui le porte

L'anneau fait ce que font les bons anneaux : il te garde dur plus longtemps, pendant que les tentacules joueurs ajoutent un supplément de sensations. Il est ajusté, confortable et conçu pour rendre tout un peu plus intense, sans en faire des tonnes.

Pour celle ou celui qui chevauche

C'est sur la surface du grinder que ça devient intéressant. Des nervures et des détails texturés qui réagissent à la pression et au mouvement, plus un emplacement pour un bullet vibrant si tu veux monter l'intensité. Parce que parfois, « bien » doit devenir « oh la vache ».

Un mot sur le lubrifiant et la finition

Le grinding, c'est mieux avec du lubrifiant. C'est de la physique (probablement). Prends un bon lubrifiant à base d'eau, mets-en plus que tu ne le penses nécessaire, et c'est parti.

Platinum Silicone

We use platinum-cure silicone for every single product because honestly? You deserve toys that are safe, durable, and feel as good as they look.

What makes it so special?

It's non-porous, which means when you clean it, it actually gets clean clean. No sneaky bacteria hiding in microscopic crevices. No weird smells developing over time. Just pure, body-safe silicone that stays hygienic no matter how adventurous you get.

Plus, it feels incredible. Like, genuinely fantastic!

Secure Checkout

We accept credit cards, debit cards, PayPal, ClearPay, Sezzle and Klarna. All secure, all simple, all showing discreetly on your bank statement.

Shipping to Royaume-Uni

Discreet Shipping

All our toys arrive in the most boring brown boxes imaginable. No logos, no winking emojis, no hints. Just you, your package, and absolutely zero awkward small talk with delivery drivers.

Returns

Look, we get it. Sometimes things don't work out. We've all been there.

You've got 30 days from when your package arrives to decide if you want to return something. Just make sure the item is in the same condition you received it — unused, with all its original packaging and tags intact.

For more info here's our full returns policy.

The ridges respond to pressure and movement, and the tentacles sit high enough that lining up takes seconds, not choreography. Works across a real range of bodies (plus size thighs included, gladly).

Stretchy enough to roll on without a wrestling match, then it holds position so nobody has to stop and rearrange. If you want the bullet pocket, add a bullet at checkout, the hole only exists when you order one.

Pick your firmness and lean soft, this is a grinder, not a dildo. Super soft keeps its shape session after session.

Quality product

Opted for the tentacle grinder cock ring with premium vibrating bullet. Ordered super soft in surprise me, colours and textures are amazing. Feels good on and no complaints from my better half! 😜

The best we own (says my wife)

Perfect like expected

I got the cock ring with the surprise me premium and silky smooth upgrade options.
The colors are amazing and the silky smooth makes it even more special.
I can't wait to try it out tonight!

Good cock ring grinder

Good cock and ball ring
Good grinder
May have got too a firm material, a the softer may be better

A very Unique Toy

So first off, the staff went above and beyond for me and I am super impressed! The colour is gorgeous, the firmness is soft and feels wonderful, and the texture is just perfect!
I have never had any kind of grinder before, so ofc I ordered three different ones!
The only downside is this toy does not work with my anatomy for me to ride my partner, but it works wonderfully for him to be on top, so all in all I am happy with it.

The Best toy out there right now!

This toy has everything! A cock ring for my partner that I can grind on And it has an option to slide in a bullet? Life changing. I usually don't like being on top because it doesn't do anything for me, the pressure points are all wrong and I don't get the stimulation I need. That has changed with this toy. I get all the stimulation I could possibly want and I want. It. All. I haven't been able to find another toy as well rounded as this one anywhere else.

Please please please make more cock ring grinders like this and I will buy them all!

Best toy we’ve used

We ordered in UC colours and in super soft firmness, along with the UC bullet.
I personally found this to be the best toy we’ve used. The material was a nice feel and the bullet had so many settings that it kept me on my toes!
We’ve used cock rings from other companies and I always found that they moved a lot, which when you’re in the moment can really put a downer one the experience!! NOT with this one! Everything stayed exactly in the spot it was meant to, and even the hubby said he felt no urge to rearrange a thing!

bullet hole isn't there! Don't choose medium

Great looking toy, we went medium for firmness and wish we hadn't, it's too tough for this use but went for it as normal like our dildos more rigid, find this hard to use in medium toughness, we didn't add the bullet vibrator as have loads of bullet vibrators already which we were excited to try with is, however it shocked us where the hole for the bullet doesn't exist unless you select a bullet to be added, very much disappointed in this product, however the mystery toy we got with it and upgraded to medium size is a big hit and feels amazing, next time will be upgrading to large for the free toy, selecting a softer material for a grinding toy and making sure the vibrator hole is always there, the toy looks great and colours are wow

Hi there,

This has been resolved. If you have any further issues, please email sales@uncovercreations.com.

Way to soft.

I went with "the most popular style" of super soft. It's so soft it's almost useless for grinding on. Would absolutely not recommend

Best toy I own... yet!

We added the silky smooth finish and OMG it is sooooo worth it. It's comfortable for him, and so incredible for me. Recommend 100%.

Both of us enjoy it

Wonderful enhancement to a good time. Wife loves the little bumpy knobbly bits, I like that it's stretchy enough to put on easily.

Gorgeous

We got it with the vibrator bullet hole and that was a win. It fits comfortably around the dong and doesn’t move to the side. Don’t forget to put some lube on it ✨

Wonderfully fantastic

The toys are one thing (soft, smooth, feel great under you, packed nicely, and beautifully designed) but also the team behind them consists of the most helpful and nice people in the business. Kind and understanding, ready to resolve any issues that might occur. 10/10

Great toy, one downside

We had a lot of fun with this grinder! It was Super Soft and damn they weren't kidding. Wonderful feel for me, the bullet and grinder were great for her, the only issue was the ball ring. It was a bit large. Like I don't think I have small balls, but in the heat of the moment, they kinda pull back into my core and in doing so, the ball ring slips off. I mean, not that much of a downside, but a smaller hole for the juevos would be better. Otherwise great toy. Fit the ole shaft well, vibrator was strong af, and she could bring or ride as she pleased. Cums all around!

Whew Mercy

I could seriously go back for seconds and thirds on this thing, wow. Great simulation and with a little lube, no pulled pubes. My partner and I both enjoyed this one. The tentacles are high/ deep enough there was very little work in getting it right where it needed to be, concerning my plus size vulva and thighs.

Where do I begin!?

This was my first toy from these guys and it did not disappoint at all! Me and my partner were excited to try it out and once it arrived, it gave both of us a very satisfying finish. We ordered it as super soft, while my partner was worried about it getting damaged, it stayed intact and felt nice for the both of us! The bullet vibrator is a must for this!
We haven’t tried it this grinder is just as good in other positions but it definitely is an encouraging treat for me to ride my partner more!

Hi there! We are so happy to hear that our Sinnovator Tentacle Cock Ring Grinder gave you and your partner a satisfying experience. We always recommend using the bullet vibrator for added pleasure. We're glad to hear that the super soft option worked well for you both. Thank you for choosing our product and happy riding!

Product FAQ

Qu'est-ce qu'un grinder ?

Les sextoys grinders sont des jouets spécialement conçus avec des surfaces texturées, pensés pour se frotter et pour la stimulation externe.

Ils sont faits pour créer une friction délicieuse contre tous tes points sensibles externes préférés, que tu t'amuses en solo ou que tu fasses monter la température avec ton ou ta partenaire.

Si tu as une vulve, c'est comme vivre le moment « au-dessus » parfait quand tu veux. Et si tu as un pénis ? Enroule-le et tu t'offres une fête du plaisir ultra texturée !

Pourquoi on est aussi excités par le frottement ? Parce que parfois, les plaisirs les plus simples sont les meilleurs ! On remet au goût du jour cette façon naturelle et intuitive de se faire du bien, un peu oubliée au milieu des jouets « traditionnels ».

Le meilleur ? Il n'y a pas de mauvaise façon de s'amuser avec un grinder. Que tu voles en solo ou que tu pimentes tes jeux à deux, ces jouets sont faits pour trouver ton rythme et assumer ton plaisir.

Qu'est-ce que l'option bullet vibrant ?

Tu veux faire passer ton grinder au niveau supérieur ? Ne cherche plus ! Tu peux maintenant ajouter un trou et un bullet vibrant télécommandé directement dans la base de ton grinder. Boum ! Grinder vibrant instantané !

On s'est même assurés que le trou s'adapte parfaitement à la plupart des bullets, pour que tu puisses utiliser le tien ou le nôtre. Prépare-toi à une expérience de grinding sans pareille et sens ces vibrations intenses dans tout ton grinder !

C'est quoi, la finition ultra-douce ?

La finition ultra-douce a été retirée de notre gamme de finitions (on ne garde que ce qu'on peut livrer à l'identique à chaque fois). Pour retrouver cette même sensation douce et glissante, associe ton jouet à un bon lubrifiant à base d'eau. Bonus : c'est toi qui décides exactement de la quantité et du moment où en remettre.

Quelles sont les différentes options de couleur ?

Nous proposons 6 styles de couleur différents, mais tous ne sont pas disponibles sur chaque produit.

Surprends-moi Basique - Laisse la décision entre nos mains expertes et nous choisirons une couleur unie qui met en valeur ton jouet.

Surprends-moi Premium - Laisse-nous décider et on se lâche avec deux couleurs ou plus. On adore ce choix, car il nous permet d'expérimenter avec toutes nos couleurs, et il donne souvent nos plus belles coulées.

Uni - Une seule couleur répartie uniformément dans tout ton jouet

Dégradé - Deux couleurs fondues progressivement l'une dans l'autre. La couleur 1 sera au bout de ton jouet et la couleur 2 sur la tige et la base.

Marbré - Deux couleurs combinées pour un effet veiné rappelant le marbre classique.

UC Trademark - C'est une couleur propre à chaque produit. L'image principale du produit montre la couleur UC Trademark.

Pour plus d'infos, jette un œil à notre guide des couleurs.

Pourquoi utilisez-vous uniquement du silicone platine ?

Nous utilisons du silicone platine pour que tu aies un jouet non poreux (quand tu le nettoies, il est parfaitement propre et ne peut pas transmettre de bactéries), sans odeur, sans danger pour le corps et avec des sensations fantastiques.

Pour en savoir plus sur le nettoyage de tes jouets, lis notre guide d'entretien des sextoys.

À quoi ressemblent vraiment les couleurs ?

Jette un œil à notre guide des couleurs pour voir exactement à quoi ressemblent nos couleurs. Mais garde en tête que chaque jouet est coulé à la main : il n'y en a pas deux identiques !

Les grinders sont-ils livrés avec des sangles ?

Oui, les grinders sont bien livrés avec des sangles ! Chacun comprend deux sangles en nylon noir de 2,5 ft (0,7 m) de long, avec boucles à déclenchement latéral rapide. Tu peux le fixer sur un oreiller, ta main, ta cuisse ou ton avant-bras pour te frotter en mode mains libres.
