Perfect Size, Shape, Everything.

This is an average-sized dildo that leaves a huge impression! It is the perfect size and shape for me; fills me up without hurting my cervix. Made of high-quality silicone with dual-densities, it feels just like the real thing. Easy to clean, which is good because no storage bag means it picks up quite a bit of lint.

Use

This is an extremely well made dildo that is made of material that is safe for everyone. Two densities of silicone are used to create one amazingly realistic penis that is as good to the body as it is to the eyes. A hard inner core adds stability, making it excellent for thrusting. The softer outer layer makes it feel so realistic. Any beginning or advanced toy user will be able to appreciate the quality and design. It is anal-safe and harness compatible.

Material / Texture

As stated on the box, this toy is crafted from 100% ultra-premium platinum silicone. This means no odor or taste. It does mean that this toy has a little drag, which is easily remedied with the use of a little water-based lube.

In use, this toy feels extremely realistic. Heat it up under some hot water and you may not even notice the difference. The outer layer of silicone is very plush but the inner core adds stability and a realistic feel (more on this below, in the "design" area).

Design / Shape / Size

This dildo is made of two different densities of silicone. The outside is plush, while the inside has a hard (but still slightly squishy and bendy) core. The head is extremely squishy as there is no core until right after the head ends. The flat area right at the bottom of the shaft on the base is also super squishy, so I think a few different sizes of o-rings will be able to fit around it easily.

In comparison to my VixSkin Raquel, this toy is definitely not as soft. Raquel's outer layer of the softer material is much thicker, meaning it is also more floppy. In use though, they felt extremely similar. Raquel can bend completely in half without any complaints, making a donut shape. Mark bends about half as easily; you really have to press hard to bend him in half.

If I were forced to choose between the two, I believe I would ultimately go with Mark.

Mark is very average in size, and for this I was grateful. He managed to give me that deep-penetration feel that I love but he didn't pound against my cervix like some toys do. I felt him brush against it a couple times but it was a gentle caress. He felt filling, in this awesome, just-right sort of way. I didn't feel stretched out. I felt like he was meant for me. However, virgins might have troubles with him and size-queens will undoubtedly be disappointed.

I would say Mark has a semi-realistic because he does have a few veins and a defined head, but he isn't as realistic as some I've seen. I couldn't feel any of these veins while in use. The head is a smoother silicone than the rest of the shaft, and that helps with insertion. Although, I still needed a little water-based lube to be able to thrust like this toy makes me want to do.

Performance

The dual-density on this toy is fantastic. This is one of those toys that makes you want to stay in bed with it all day, but it still good for a quickie.

I recommend grabbing this and your favorite clitoral vibrator and enjoying some personal time. For me, this resulted in some of the most intense orgasms I've ever had. Granted, if you really hate penetration and you only want clit action, this toy won't be good for you. But, if you want a realistic feeling dildo, I highly highly recommend this one.

The bottom of this toy is smooth shiny silicone, made of the hard variety of the inner core. I believe it would be good for harnesses but as I don't have one I can't be sure.

Care and Maintenance

Because this toy is made of 100% pure silicone it is completely sterilizable, by any method you choose; i.e. boil, bleach, soap/water, dishwasher etc.

However, because it's silicone, you cannot use any silicone lubes without running the risk of damaging the toy. Again, use only water-based lubes with this. I will repeat this again as necessary because this toy will last you a lifetime if you care for it properly.

This toy doesn't really come with a good storage method. No bags are included and the plastic box is less than ideal. You can store it without putting it in its box, but it picks up lint and hair. For now, I'm keeping it in a gallon-size zip plastic baggy but I'm going to buy a drawstring bag for this toy. It deserves it.

Packaging

Mark came packaged in a clear box inside a clear clam shell. The clam shell doesn't have any kind of snap to hold it shut, the halves just close against each other and slide into the outer plastic box.

There's nothing risque about it, but it isn't what I'd call 'classy'. This packaging is the biggest problem I have with this toy, because I don't like to leave it just laying in a drawer but the plastic takes up so much room, and is really flimsy.

The box does have some helpful information on the outside, stating it's 100% Ultra-Premium Platinum Silicone, that it's hypoallergenic, hygienic, phthalate free, odorless, tasteless, boilable, bleachable, and completely non-toxic. All of this was stated in 2 paragraphs and I've found all these statements to be true.

Personal comments

My Dad and this toy both share the first name Mark, which is why I choose to review the chocolate color. It's just about the exact opposite of my Dad's skin tone.

I looove this color though. It is a deep, rich brown that looks almost black when the light is low.

Experience

When I first took this out of the box, I was a little underwhelmed. Average width and average length make for a very unassuming toy. I was happily surprised with my experiences with it though, and if I weren't addicted to trying new ones, I could say for sure I wouldn't need another dildo.
Follow-up commentary
This is still my favorite 'go to' dildo. I like to have others for variety, but something about this toy just fits me so perfectly.

I cannot even pinpoint what makes this toy so incredibly amazing; perhaps some mixture of the dual-density silicone with a size that is filling but not stretching. It might be the gently curve in the shaft that teases all the right places, but feels so remarkably lifelike.

Seriously. Just buy this toy (or at least an O2 dildo) and see for yourself. Treated right, this toy will easily last your lifetime. Even though I received this toy for review, I would gladly pay full price (and even double that) for this phenomenal dildo.

    If it was just a bit longer insertable, I'd be sold.
