My Verdict

This intergalactic vulva is alluring and seductive and feels fantastic to ride. The squishy soft version is the softest silicone I've ever felt and the supple ridges flex and move as you grind over them. It's a really unique sensation that I've not experienced from any other sex toy, almost like oral sex. I think this is fantastic for long sessions where you want to slowly build arousal rather than going from 0-100.

Personal Experience

My Personal Experiences with Uncover Creations The Synstyl Grinder

A Venutian Vulva

Reviewing a silicone alien vulva definitely wasn’t on my 2025 bingo card, but I’m not mad about it! This was the first time trying a grinder and although I thought it would be something I enjoyed, I didn’t really know what to expect. When I opened the box, I was thrilled to see a miniature version of the Synstyl Grinder and couldn’t wait to find a spot for it in my collection of oddities shelf. It also came with a lovely note letting me know that my grinder was made by Matt! The personal touch makes this item so much more special!

Partnered Play

My partner suggested strapping the grinder to his leg during PIV sex, and wow what a stroke (or grind) of genius! There were a couple of positions that really hit the spot. The soft ripples of the silicone felt almost like a tongue and the added sensation felt fantastic! I was genuinely surprised that it was possible to use during penetrative sex. It’s also worth nothing that Uncover Creations also make a grinding pad that has a hole for a penis or dildo.

Riding Solo

I also tried the grinder strapped to a chair for solo play and loved the new sensations it provided. It felt like riding a partner’s face, and I really enjoyed having my hands free. I have to say, while I did orgasm, the build up was so much more fun! While I was able to climax using just the pad, it’s also possible to use a wand or bullet vibrator for a boost of power. I’m already thinking of all the fun ways to use it! Some rope or restraints could be a fun addition to the chair set-up, and I can see it being a great way to get more stimulation while pleasuring my partner.

Design

The intricate rippling textures and marbled colors of the Synstyl Grinder are mesmerising to look at! While I've never been into the idea of alien role play, I really love the otherworldly vulva design and I find it sexy and intriguing. I also think it could be fun for simulating oral sex. It's also really fun that you can design your own custom color combinations! I requested the color that's on the website simply because I loved the vibrant swirls of orange and pink. The only thing that I'm not a massive fan of is the black nylon straps. I would love if they came in a different colour or in silicone, but that's a very small detail that doesn't detract from the overall design that much.

Ease of Use

The addition of straps makes this a much more versatile grinding toy! I love that I can strap it to one of my Wanda sex toy mount, to a chair, or to my partner's body. It can take a little experimentation to find the right position The depth of the textured pad also makes it easier to get a good amount of contact. The silicone feels a little tacky, but a small amount of water-based lube actually goes quite a long way, which is always nice!

Quality

Uncover Creations The Synstyl Grinder Quality

I really cannot fault the quality of Uncover Creation's work! This grinder is a beautiful piece of silicone art! There are no imperfections in the silicone and it's delightfully soft and squishy. As it's one piece of silicone, it feels very sturdy. The only weak points are the holes where the straps feed through, so I am a bit cautious not to pull on them too hard.

Price

Uncover Creations The Synstyl Grinder Price

Considering each item is hand-poured, based on your custom color and firmness options, I think the price is very reasonable. With the correct care it's also going to be a toy that lasts a long time. Plus, it came with a free mini grinder that has taken pride of place on my bits and bobs shelf. On top of that, with each order, you get a 20% discount code for your next order.

Performance

I opted for the squishy soft silicone option and I'm SO happy I did! The soft ripples have just the right amount of texture and I really like that they have some movement to them. As well as the rippling texture of the all the ridges, the opening in the center creates suction-like feel. The whole experience feels a little like riding a partner's face. The depth of the pad also works really well and allows for a good amount of contact. The center is firm enough that it holds it shape even while sitting on top of it.

Packaging

Uncover Creations The Synstyl Grinder Packaging

The Synstyl Grinder came packaged in a plain brown box and inside the grinder was wrapped in black tissue with an Uncover Creations label on the front. Aside from some recyclable packing protection, there was a mini grinder and hand signed note. I loved the thoughtful extra features and that there was no plastic!

Materials and care

Uncover Creations The Synstyl Grinder Materials and care

The grinder is made from premium quality silicone, making it non-porous and body-safe. It's best used with a squirt of water-based lube but I was pleasantly surprised that I didn't need to use much. While silicone is easy to care for with soap and water, all of the ridges require more attention when cleaning. I like to use some fragrance free soap and water and really lather up the whole grinder, making sure to get in all the small ripples. You could also use a very soft cloth or sponge but I would avoid using anything that could damage the soft silicone. After drying it with a towel, I also leave it out to air dry so it's not damp when I put it away. It's a little tricky to keep the straps dry so they need time to dry as well. You could take them out if you want to boil the silicone though but it's a little too much effort to do each time you use it. My only complaint is that it doesn't come with a storage bag — that would have been the icing on the cake!
