The Tantus Luke O2 is one of the few realistic dildos that I’ve fallen in love with. I’m fairly picky when it comes to more realistic dildos, because I prefer them to look more like my husband’s penis. The Luke O2 fit that bill, and the fact that it was a Tantus O2 product just made the deal sweeter. The O2 Cush and O2 Flurry completely spoiled me. Once you go dual density, it’s difficult to go back.
O2? Dual Density? What?
The O2 line from Tantus are dual density toys that are designed to have a realistically familiar feel. The SuperSoft™ outside and the hard muscle core are both made of Tantus’ own unique blend of 100% Ultra-Premium Silicone. Aside from that, the Luke O2 also has a dual finish; a soft matte finish on the balls and shaft, and a smooth shiny head.
Basic Details
Insertable length: 5 3/4"
Circumference: 6"
Diameter: 2"
Harness compatibility: O-ring compatible. You’ll need at least a 2” ring.
Weight: 1.3 lb
Anal-safe
Keep in mind that I wear a size 4 wedding ring, and my hands are tiny.
Material: Silicone
All Tantus toys are hand-made in the U.S.A. from the highest quality 100% Premium Platinum Silicone (If cared for properly, it will last a lifetime). That means they’re hypoallergenic, hygienic, phthalate-free, odorless, tasteless, boilable, bleachable, and completely nontoxic! They are also manufactured 100% green.
The Luke O2 retains heat well, so pop it in bowl of warm water before play to make it feel even more realistic. Just be careful not to get the water too hot!
Texture/Firmness
The Luke O2 features smooth balls and a shaft with nicely pronounced veins in a matte finish, which feels decently similar to skin. The head is very smooth and shiny, with a bit more drag to it than the matte finish. There is a pronounced corona (lip of the head) and a slightly exaggerated frenulum which has uneven foreskin ridges around the toy the make things look a bit more realistic.
The head and balls, which lack the firm core, are very squishy. I can easily squish and pinch them with just two fingers. The shaft is just as squishy, but has a very dense core. I can bend it, but it does take some effort. The softer material on the outside of the core is thicker at the base of the shaft and gets thinner towards the head. It does feel very close to how an actual penis would.
The design of the Luke O2 seems to me to be very similar to the VixSkin LoneStar. Instead of picture-bombing my review with large comparison photos, you can click the green text to view a slideshow of the larger photos. They are the same height, it’s just that the base of my VixSkin LoneStar sort of warped over time from being stuck in a certain position.

Lube
Use only water-based lube, as silicone lube can damage silicone toys. The matte finish on the shaft holds onto lube well.
Cleaning
You can boil the Luke O2 for 5-10 minutes, stick it in the top rack dishwasher, wipe with a 10% bleach solution and rinse, or simply wash with soap and water. Toy cleaners and wipes are also fine.
Storage
Silicone is pretty much a magnet for hair and dust. So, keep the Luke O2 somewhere safe from dust and hair, where it won’t get squished or touch other toys. You can keep it in a Ziploc bag, a toy storage unit, the box that it comes in, or wherever it will be stay safe and clean.
Packaging
The Luke O2 that I received came in a clear poly bag sealed with a folded Tantus label. Information about the company and silicone are provided, but there’s nothing in particular about the Luke O2 on the packaging, or any cleaning/care instructions. Instead, you’re directed to the Tantus website.
The bags aren’t a normal thing, though. If you decide to get the Luke O2 for yourself, it will come cradled in a clear plastic box along with about the same amount of information. All Tantus toys pretty much come in the same packaging. So, to the right is the packaging for another Tantus toy.
Opinion
I always say I’ve never had a Tantus toy that I haven’t liked, and that still holds true. Personally, I have nothing to complain about; perfect shape, perfect size, dual density, lovely texture, and I love that Tantus is doing a dual finish thing now. I’ve actually got a couple other Tantus dildos that have the same dual finish, and I love them.
The only issue that I’ve seen is that it would be better if it were curved a bit for harness play. Otherwise, love it!

I've encountered the same problem with my LoneStar. It's been stored upright on its base since I purchase it, but after about six months the base started curving upwards (becoming convex). It now doesn't stand up securely and likes to topple over if provoked. It seems as though that the softer layer over the balls and shaft have contracted over time, pulling the base up and preventing it from sitting flat.
Hmmm... I thought it was because I had it sitting half on a shelf and half on a plastic bin, but yours did that, too, just sitting on a flat surface? That's odd. If it's the soft material contracting, I guess I'll have to keep on eye on my Luke O2, and see if that happens with it, too. Thanks for letting me know! I just figured it was my fault.
Yeah, it was kind of interesting. I'm going to hazard a guess that it's because I clean mine boiling or dishwasher (depending on whether actual dishes need to be washed). If the two materials have different expansion coefficients (the degree to which a material expands when it heats up/cools down) one would expect a warping if the materials do not return to their exact original dimensions when cool. If the softer material slightly reacts with time and heat with the harder material, it could become somewhat more dense, and draw up the base. Of course, this is all conjecture, but it would be interesting to poll the Eden audience and see whether this is a common occurrence.
Most definitely. It would be an interesting study.
