The Best Man I've Ever Met!

Note that my review is based only on anal experience, and I am not an expert on the functionality in vaginal use. Beside that point, this is my far the best toy I have ever used. It is an average-sized, dual-density silicone toy made by Tantus. It has a soft head, which makes direct g-spot or p-spot stimulation difficult. Mark is realistic with out being over the top, and mostly smooth with slight veining. Its harness compatible with a wide base.
Perfect size, realistic, easy to clean, harness compatible, great material
Lint magnet, head a little too soft, no silicone lube
Rating by reviewer:
extremely useful review


Mark is a great all-around toy for all uses. Though I don't have a vagina, so my knowledge is limited, it seems like it would be average size that would great for everyday use. Anally, this toy is great! It is a perfect medium size for a novice to intermediate user. The toy has no curve so it doesn't provide direct stimulation to the prostate. The soft head makes insertion more difficult, but very possible if you have taken a toy with a similar size. Mark is also harness compatible and has a wide, rigid base.

Material / Texture

Tantus really does seem to make the best toys, and this is no exception. It is 100% platinum silicone, nonporous and phthalates free. Mark is unbelievably soft, and is mostly realistic, while not being over the top in a way that I've found many consider disturbing. It is smooth and has slight veining and rippling in the shaft. Mark has a dual-density design;the head and 1-2 mm of the shaft are both comprised of the soft material, while the inner core is quite rigid. There is an extra few mm of the less dense silicone on the underside of the dildo compared to the top. The soft head could be considered a negative to some, although I love it, because the toy cannot deliver firm g-spot or p-spot stimulation. I've also found that the soft, outer-silicone, makes with dildo easier to take fully when you are using a toy larger than you usually do.
    • No odor
    • Not porous at all
    • Smooth

Design / Shape / Size

This dildo is average sized and quite realistic. The length is a little over 6", and 5 1/2" insertable. The width is 1 3/8", which makes this a medium thickness toy. For vaginal use, it wouldn't provide an extremely full feeling and would be good for everyday use. When used anally, a bit of experience is needed as it is not meant for beginners. The realistic nature of this toy is not only visual but it also feels quite real. It is very soft, and the dual-density makes it feel like a real erect penis. There is also some veining and the underside of the head is anatomically correct; there is a slight slit and frenulum. The dildo has a slight curve, but nowhere near enough to be considered a g-spot or p-spot targeting toy. The base is very rigid and sturdy, making mark perfect for harness use.
    • Medium sized
    • Realistic


The shining note about the toy is the realistic feel, which I have already discussed extensively. The size is great if you are looking for a medium vaginal dildo, but the small curve will not give direct g-spot stimulation, but enough to get most women off. If used anally, the soft head could be problematic if you have never used a toy of this size, but once you get passed this, the dildo slides in nicely because of the soft and smooth texture.
    • Comfortable
    • Not discreet at all

Care and Maintenance

Because Mark is made from silicone, cleaning up couldn't be easier. You can simply wash it with antibacterial soap and water, boil it for 5-10 minutes, or put on the top rack of your dishwasher. You may want to wash before use because silicone attracts lint like nothing else. You way want to store in a plastic bag to keep lint to a minimum. The only downside to using silicone toys is the fact that the can only use water-based lube with them.
    • Easy to clean
    • Easy to store


The packaging Tantus uses is simple, but impractical for storage. It is a clear plastic box that has a molded plastic interior to hold the toy in place. The box is not meant for storage as it is a pain to get in and out and the box tends to fall apart over time. There is a decent about of generic information about Tantus toys on the sides, which is nice if you are unfamiliar with this company and their products.
    • Minimal
Follow-up commentary
The Mark is still one of my go-to toys for anal play. It has been demoted slightly since I bought my first VixSkin toy, and I prefer that to the O2 on most occasions. Anyway, this still has a place in my collection for when I need a filling anal dildo.

    Thank you for the nice review I have Adam, but Mark seems like he would be more fun for anal play when I can comfortably handle that size.
