The super vac-u-lock - sex toy by Doc Johnson - review by That Man from Mars

A Hands-on approach overall

The amount of quality, versatility, and affordability is brilliant in itself. But above all my favorite thing about this dildo is that the entire time I didn't feel like I was using a dildo. That was my penis. Plain and simple.
quality silicone, realistic, affordable, versatile
might be too much texture for some
Rating by reviewer:
extremely useful review


For one, I'm the kind of guy who likes to feel a bit of texture to my manly parts. It makes things more realistic and enjoyable, and this little cock does a brilliant job of that. It's a bit more textured than the average penis, and I can't say I'm complaining about the dramatization-- nor is my lover, for that matter. The head has a great flare that can really be felt and is able to stimulate those otherwise more sensitive and harder to reach areas.

Being made of quality silicone, it retains body heat well, which is very important if you want that 'natural' feel. Highly recommended for transguys and anyone else who wants it to feel like the real deal. It's not too long, not too thick, but if you want some serious girth, you might want to try something else. We didn't have any problem.

Material / Texture

You might be shocked to know that given the quality of silicone, this little guy is a steal. I've yet to find a cock that matches in quality. It's easy to clean, non-porous, retains warmth well and is quite sturdy. Latex free means you needn't worry about latex allergies, and my favorite thing above all is the feel. It feels about as realistic as the real thing. For me, that was a big time winner.

All that goodness aside, it's pretty tough. Great for rough play and handles well without the floppy might-break-any-moment qualities of jelly dildos. It isn't sticky but given the detailed texture you might want to keep a bottle of lube (water based) in hand.
    • Bumpy
    • Not porous at all
    • Rigid

Design / Shape / Size

Did I mention how much I love the slightly exaggerated but realistic look? Let me repeat myself: it's fantastic. I'm especially pleased that it comes with balls, which can be rough to find on a good, detailed dildo. The balls can get in the way a bit with a loose and low-grade harness (which I unfortunately had), but a nice tight ring should hold it fine. It's compatible with many of the harnesses on EdenFantasy, and even better, vac-u-lock systems. You can pretty much mount this baby anywhere you want-- to your crotch, to a shower wall, whatever.

Haven't tried it with a suction cup, but the harness is just fine. As stated before, I had a ring that was a bit too big and made things a little floppy, but a tight ring fits fantastically and the balls didn't at all get in the way. I was delighted that it didn't rub against my skin awkwardly and held firm. I often get bruises (alright, I'm a wee bit aggressive) and chaffing from the base of a dildo, but this one is so well made and smooth that it was never an issue.
    • Comfortable
    • Easy to use
    • Not very discreet

Care and Maintenance

Washing dishes. Pretty easy, right? It's not really any different. Pop it on the top rack in the dishwasher and walk away. That or you can toss it in a pot of boiling water a couple of minutes, or use the classic 10% bleaching solution. Unlike a few other dildos, I haven't had to really deal with the 'sticky' problem. That horrid occasion where you find your dildo is picking up every cat hair and piece of lint to float in a ten meter radius. It's pretty clean and easy to maintain.
    • Easy to clean
    • Easy to store
    • Non-sticky


Fairly simple package. Nothing special-- a plastic casing that is lovingly shaped around the dildo and relatively nondescript. I wouldn't suggest keeping or reusing it. But hey, it's a dildo. You can stick it pretty much anywhere. In a drawer, in a shoe box, in that hidden spot on the top shelf of the closet so dear mom doesn't have a heart attack upon accidentally baring witness.

    Wow! I didn't realize the price had gone down on this! I have been wanting a realistic silicone one that has bigger balls than my "Hank" dong. I paid twice as much for it and at least with this one, it's vac u lock compatible, which will come in handy for versatility! Thanks for the review!
  • Pleasure Piratess
    Wow, can't believe that is silicone for that price! Thanks for the review.
  • Antipova
    Wonderful review! I'm really surprised to see silicone for such a low price, too.
  • ToyGurl
    Thanks for the wonderful review. I really love the way you add a presonal touch to your reviews and let the readers know why YOU love the toy and how you like to use it. A lot of people these days just stick with the basic "this is for anal sex" or "this is for your clitoris" stuff. Awesome
  • P'Gell
    That's an amazing price for a silicone dildo! My Tantus was more than 3 times the price (and it doesn't even have any balls.)

    Does this guy work for packing, or is it purely for sex?
  • That Man from Mars
    Definitely not packing, it's too firm and won't bend to save your life.
  • The Curious Couple
    Great review, thanks!
  • married with children
    great review, thanks. sounds like a good toy for a great price.
  • PassionQT
    I also own this one and the texture was unbearable for me. No matter how much lube I used, it did not improve things. It may be silicone, but there's better out there if you want something more realistic feeling and without the ridges >>>> VIXSKIN!
  • That Man from Mars
    It really does depend on what you like. The texture is quite intense, so I can definitely see it being too much for some.
