The Synstyl Grinder

Best Seller
Sale price£59

A textured flower of ridges, folds and crevices that feels less like silicone and more like grinding on someone's face (a compliment, we promise). If you're wary of all that texture, don't be: it's soft enough to glide, firm enough to stay put, and made from body-safe silicone that puts up with a jolly good dose of lube. Weighty and dense enough to hold its ground through the most vigorous of cowgirls.

Ridges everywhere

Every curve, fold and crevice gives you something different depending on how you sit on it, so no two grinds are quite the same. Soft enough to glide across, textured enough to feel like you earned it.

Strap and go

Comes with two 1m nylon straps and quick release buckles so you can fix it to a pillow, thigh, forearm or hand and go completely hands free. Add the optional bullet pocket if you want a little buzz in the mix.

Heavier than it looks

Body-safe silicone with proper heft, so it stays put rather than wandering off mid session. All those crevices ask for a slightly longer wash (worth it), and it pairs well with a good water based lube, so you decide how much slip you want and when to top it up.

What our customers say

The overwhelming praise is for the looks and the texture, with the soft, squishy firmness and the "riding someone's face" sensation named again and again, alongside genuinely helpful customer service and how gender affirming trans customers find it. The straps and the bullet pocket draw the most consistent criticism, with the buckles loosening or not cinching and the bullet cavity sitting too deep or too narrow for standard bullets. A few smaller people also found the width more than their body comfortably wanted.

First Grinder! Used in “Reverse” + Magic Wand

Oohoo she’s so pretty!! And so gloriously noisy and silky and textureddd! 🎉🎉

Ok so, as someone newly exploring their orientation, I wanted something vulva-esque. I also needed a nonpenetrative toy, and this is my first grinder. I was not disappointed.

To explain how/why I used it, for anatomical context, I have a tiny entrance and a longitudinal septum. So penetrative toys, and anything else, sadly doesn’t fit and is painful unless it’s a single finger or maybe a tiny gspot vibrator after a lot of warmup. My body has always made me feel defective (society glorifies PIV, after all), but I’m looking for workarounds and how to accomodate myself and my sexual preferences, hence this toy.

(So thank you also for the free XS dildo but it’s still way too big for me 😔 I could maybe try it for anal, since it has a flared base).

I also have hypermobility and trying to do cowgirl on a pillow, let alone kneel for more than a minute is painful for my spine and hips which subluxate. (Although I could maybe try being crosslegged and curling myself over a pillow but it’s still uncomfortable for my neck/shoulders and I’d need to play with configuring pillow shapes.)

When playing with toys and for maximum comfort and no joints rolling out of my sockets, I prefer to lie flat on my back. Maybe feet in there air to start. Like a beetle lol 🪲

So, after discovering grinders were even a thing, I suspected they were maybe the way to go, but knew I wouldn’t be able to use them in the traditional manner, and wanted to test my theory…

So, I used the Synstyl like a “reverse” grinder, where I attached the toy to myself. I put the straps around my upper thighs (which was also fun as it felt a bit like I was wearing a harness or strapon just minus a dildo heh), and by lying on my back I let gravity hold the toy in place against me with the straps. I put plenty of water based lube in between me and the toy, then used my magic wand sans lube so it didn’t slide against the flat back and went to town. It worked exactly how I had intended yaaaay!!

God I love the texture with lube, it’s so smooth and silky 🤤 All those bumps and firmer ridges towards the top plus vibrations from my wand?! Pumping the wand against the flat back of it in the middle to make delicious squelchy sounds between me and the slightly hollow open lips?! Pressing the dry wand head so it “sticks” to the flat back and then rolling/pushing so the grinder slides against me?! Then slipping the wand in between me and the toy and for maximum vibrations?! Oooohoo yeah 😏

There’s another reviewer who mentioned their height and how the grinder is broad between their legs. Yes, as someone who is also 5’, I can attest to the grinder also being wider than anticipated, and it’s very hefty, and it could be slightly narrower. I can’t remember what firmness they got, but with the super soft firmness, it squishes easily enough for me and I personally had no issues, especially for the way I used it…

Climaxed three times in less than fifteen minutes, and I was only aiming for one 😌 Ran straight back here to leave a review, and I havent even wanted to take it off yet, I love how it feels against me. Thank you for making this excellent toy 😘

Loving Grinder and Mystery Dildo

This is the second grinder I've bought and I love this one so much! It's soft and all of the little ridges feel incredible. Also, the space for the bullet vibrator is so much better on this one than the last one I ordered; it's much easier to take in and out. My phone doesn't do the product justice, it looks gorgeous! (Also, I always love being surprised by what dildo I get, and the pure black was such a good choice.)

Excellent transmasc toy & gorgeous pour!

I bought this bc I’m transmasc with significant bottom growth and I want to stick my dick in everything, but most toys won’t accommodate my anatomy. This toy is exactly what I was looking for. The angle makes it functionally penetrable for me without too much friction or any pinching. Excellent solo or with a partner.

I ordered a Surprise Me Premium and asked for something magical. I got a gorgeous blue/purple/pink/gold combo that was clearly poured with care and attention to the mold. Silky smooth was absolutely worth it; it's a joy to touch. One great detail that stood out to me: the entire front and side of the grinder are silky smooth, but the back is still full friction so it doesn’t slide around. It's a hefty chunk of silicone; even in super-soft, even without the straps, it's very sturdy.

Very happy with the entire purchase, the quality of the pour, and the fulfillment timeline! Thanks!

Everything BUT

This type of toy my s and I have spoken about a lot; they had a task they needed to complete and this is their reward. The color and texture and detail are absolutely gorgeous and the bullet is going to do some wild things for my gg. That being said, these straps. PREMIUM toy. PREMIUM vibe. PREMIUM material.

And the straps won’t catch on the cinch. I can barely get this thing to stay in place on my thigh bc the buckles won’t cinch.

Only downside is it can't love you

Just a week in, and my brand new alien flower nymph pussy grinder and I have already gone on a good number of successful rides. I chose this one because theres an obvious hole for my clit to hide in. I like that it can give me indirect stimulation from all directions simultaneously. And also because its a pussy, sort of. Yonic enough that my brain is like "omg pussy on pussy action ♡". Fantasy enough that I dont feel like a creepy perv who stole mannequin parts from a gynecology class to pleasure myself with. Attempting to see with my minds eye the creature this artistic pussy belongs to is taking me new places. Fun for the creative types. This is my first time finding a sex toy sexy.

The sensations are great and fun to explore. Sometimes i think "maybe this is what it feels like to have a dick and put it in someone", and the fantasy feels congruent with the ongoing action. Which is awesome, because some of us with the vulva configuration want to imagine doing the fucking rather than being the fucked.

The set up is important. Flat on the bed, it kinda sucked. But on a yoga bolster, very good. My cylindrical bolster maybe places it à bit too high though; I think a rectangular bolster could be better. I intend to experiment in order to find the best mount for this lovely saddle.

I got the super soft, silky smooth options. I got the vibrator stuff too, because fomo, but I havent tried it yet.

This isnt a toy for lazy bottoms. Not at its non-vibrating state anyways. I work hard to get off, which is exactly how i like it. Orgasm is the dangling carrot that keeps me going when my abs, legs and cardio want to give out. It feels holistic, similarly to when having sex with someone. Its the kind of proper solo fucking that actually puts a dent in my sexual frustration.

This was a much needed toy for my specific needs. Im definitely gonna be on the lookout for other yonic grinders from this company. Money can't buy me love but it can buy me a toy harem.

BANGABLE ALIEN PUSS!!! Or, Georgia O'Keeffe gone wild?

So goddamn sexy. I love that I have my own customized *alien puss* to fuck my t-dick into!!! I mean damn, I was thirsting for this toy before deciding to drop the money. A good price as well, for the quality!

My colour choices were:
Dragons gold
Sangria
Glow green
And it very pretty, especially photographed alongside plants <3

This toy takes a little more time and attention to wash, or at least to feel confident I've soaped and rinsed the entirety of the silicon toy. That's the cost of all that beautiful texture.

Using some handy water based lube as well makes it feel more vivid, I mean fuck! Feels so right to grind against this toy. She has lots of curvy folds, and channels in between to hold onto the lube, keeping things wet... Oh how I need... Her? It? Zer?

The size is quite wide, from my POV as a thigh squisher. I can rub against it comfortably, but as I'm building arousal further, and feel the need to crush it into my dick as tightly as possible, I feel the bulk of it against my thighs. It is a little uncomfortable and distracting, but not to the point of pain. It's got squishness. I chose firmness level: super soft!

The toy is a bit weighty. Not the simplest option to slip into your purse or tote on the way to a hook-up. I'm keeping mine in my bedroom for mostly solo play. (If the right thigh comes by... I might just ask to strap this onto them!)

I did purchase the silky smooth upgrade also, and enjoy the smooth, luxurious feel.

A slot for bullet vibe and bullet was a good choice for me, I enjoy the additional sensation, and the convenient remote control.

I love the synstyl grinder, and would recommend it to folks who like the idea of fucking a fantasy plant or alien.

Awesome Grinder

Beautiful Grinder, colours are fantastic, super soft and squishy. Feels amazing to grind against. Very happy, would recommend to any girls who like a good grind and don't want the male-like grinders.

Absolutely Gorgeous

Honestly I have no complaints. This thing looks and feels and functions amazingly. The missing star is just due to not receiving the straps that I ordered with it. I got a premium surprise-me custom, with a bullet vibe hole. the hole is very roomy which i like because it means i can fit a variety of vibrating toys in there. The colors are VERY to my tastes and it has this subtle and beautiful angelic feel to it with the white and the iridescent blue/gray. This is my first grinder and WOW i am thoroughly impressed.

I wanted to give this toy a good number of tries before writing up my review. I have never used a grinder, and before this I have never tried grinding or humping something, so I was a bit worried this toy wouldn't work for me. I am also a plus sized person, my t-dick is pretty hidden, so that adds to this toy's learning curve, but I've still been enjoying it! It can be tricky to position myself on it properly but once I get it right, it feels great! It's really gender affirming to be able to feel like I'm penetrating or frotting against something, and the super soft firmness has a perfect amount of give and solidness to it, I think. The toy itself looks beautiful and as a bonus, the pour coincidentally ended up as my favorite color blue :)

Good stuff

This is my first foray into high-end sex toys, specifically grinders. I'm always humping pillows and legs so I feel that this was an overdue purchase. Got it as super soft, surprise me basic with a bullet hole and straps.
It's a really good feeling, takes a little to find my rhythm but don't struggle and find myself melting into it quickly. Firm enough to stay in place, soft enough to glide with little difficulty. Can comfortably put my entire weight on it without something hitting me wrong. With the right amount of lube and a bullet in the slot it drives me over the edge, sometimes in just a minute, which is unprecedented for me. I'm a trans guy so I've got significant bottom growth and it really feels like I'm rutting into someone's pussy which is what I was hoping for. Remarkably snug and hits all the right spots, definitely recommend to those with growth if a PIV-style or oral sensation is something you like. The more lube the better, no problems with grip and feels like heaven. Cleaning isn't a chore and it's fun to absentmindedly pull at and grope, so I appreciate that there's a mini tossed in for me to screw around with. Design is great, looks like coral (especially with the colour) or a Rorschach. I kind of regret not getting the silky smooth additive and marble but I'm satisfied nonetheless.
As many have said, it's pretty noisy once you start working it, hot but not at all discreet if that's a concern.
Cool colour, in tandem with the rest of the order colour-wise which is nice. Timely shipping, team was helpful and pleasant, will probably buy again in the future.

Wonderful product and amazing customer service!!

I would definitely order again!

Noisy but in a hot way! Super soft + surprise me premium

Definitely agreeing with other folks that this is one noisy-ass grinder once you get going, but the squelches are a hot plus for me—other than the obvious, yeah, there’s no privacy to be had, haha. I got the a surprise me premium and requested something “purple-y” and they absolutely delivered! I think the contrast is so pretty.

As a trans guy, it’s pretty fun to get my bottom growth bits in and around there. I agree with someone else that cleaning her feels like I’m fingering her, haha. High learning curve, yes, especially since I’ve only used the oni and venus grinders, which have more obvious “insert the protruding thing” aspects, lol.

The fun toys and the incredible customer service are why I keep coming back for more! I think this order was my third one total, and I’m sure I’ll make another one or three in the future! Thanks Jade + team!
