The super vac-u-lock - realistic dildo by Doc Johnson - review by hybridinsurge

Super duper!

The Super Vac-U-Lock is a high quality, realistic, silicone dildo. With some adjustments, it can be used as a strap-on, as a vibrator, or with a suction cup. The premium silicone is easy to maintain and soaks up heat - a very nice bonus! I believe beginners and average users will be pleased with this toy, as long as they do not mind its firmness and "veiny" texture.

Average size
Too big or small for some

Rating by reviewer:
extremely useful review


The Super Vac-U-Lock is a dildo, so it is meant for vaginal or anal insertion. This toy can be used solo or by a couple (or more). It is fully waterproof, so it can go into the shower, a hot tub, a pool...wherever!

It is a relatively small size compared to other dildos in the Vac-U-Lock system. Even though it seems a bit large at first, beginners may want to try it. The material is very forgiving. It is very flexible and soft, but still firm enough to hold its shape. Because of the flared base, I think those who want to use this for anal insertion could do so easily.

While I just bought this for use as a dildo, it can be used as a strap-on in conjunction with a harness. The dildo is fairly realistic in design, and the silicone soaks up body heat, making it even more lifelike. I bought the dildo in beige, not in shiny, bright pink. Obviously, the pink will be less realistic unless you are used to having sex with shiny, pink judgement.

Material / Texture

The Super Vac-U-Lock is made of silicone which has a rating of ten on the EF material safety scale. It is nonporous, hypoallergenic, latex-free and phthalates free. Silicone absorbs heat so you could try soaking it in warm water before use for a more realistic experience. This material also repels dirt and bacteria and can withstand the long-term friction caused by thrusting. It has no taste and an extremely slight, almost unnoticeable odor.

The toy is somewhat squishy and very flexible, especially at the base of the toy. The shape of the toy’s head is very realistic. There is a noticeable definition between the head and the shaft. The texture along the shaft is not very realistic. The shaft has a number of defined veins running around its circumference with two ridges running vertically down either side.
    • Flexible
    • Harness compatible
    • Not porous at all

Design / Shape / Size

The Super Vac-U-Lock is about 6 ½” long, and about 5” of that is insertable. The dildo has a circumference of about 5 ¼”. I think this is a good size for the average user. It may not be for people who have never inserted anything before, and more advanced users may want something bigger. However, this is one of the smaller dildos from the Vac-U-Lock system, so beginners to strap-ons may want to give this a shot, even if it looks somewhat intimidating.

This toy is definitely not discreet. It is meant to be realistic but the texture around the shaft keeps it from looking just like the real deal. The halved testicles that make up the base of the toy seem very unrealistic. The head looks and feels realistic, in my opinion. Those who are interested in an extremely realistic strap-on probably will not be happy with this toy. Those who want to pass off their dildo as a piece of postmodern sculpture should also look elsewhere.

The Super Vac-U-Lock is compatible with the Vac-U-Lock system, O-Ring harnesses, and suction cup accessories. I have not tested the toy with any of these options.

There is a pit on the underside of the toy’s base that I assume works with the harnesses. After getting the idea from another reviewer of this product, I stuck a bullet vibrator in that space. It worked very well and turned this into a vibrating dildo. This thing is a wonder!

Care and Maintenance

Because the Super Vac-U-Lock is made of silicone, it is top rack dishwasher safe. It can also be disinfected by boiling it for three minutes. I typically run mine under extremely hot water for several minutes. After cleaning and drying, I store my toy in a large Ziploc bag.

The silicone attracts hair and lint. Before using, I wipe the dildo off with a damp rag or a wet wipe.

This toy can be used with water-based lubricants. Do not use with silicone-based lubricants. I use this toy with a generic equivalent of water-based Astroglide. I do not have to keep reapplying lube because the dildo does not soak it up.

The packaging was a simple, hard, plastic, pull-open case. The included cardboard insert offers information about cleaning, product warranty, material, and system compatibility. I did not keep the packaging as a storage box, but I think it could serve as one. However, the packaging is a lot bigger than the toy and is not discreet.

I did not find the Super Vac-U-Lock’s "veiny" texture uncomfortable when it was inside. The head and its distinct ridge provided some enjoyable stimulation. The flat base makes for a convenient handle during solo sessions, and allows the toy to rest on a flat surface, such as a bed, during thrusting. I really like that the silicone adjusts to my body temperature. I would not recommend using this toy without lube; just remember to use a water-based one!

I was a little intimidated by the size and look of this toy, at first, but I typically have trouble inserting things. The second time I tried the toy, my boyfriend helped. The toy went in smoothly after I was more aroused and lubricated. It was a nice precursor to sex.
Follow-up commentary
This toy remains a favorite for solo and couple play. My BF and I find it really helpful to warm up with this toy because he is rather large, and I am rather clenched up at first. The material is not showing any wear yet. The easy clean up is a plus.
