Doc JohnsonVac-U-Lock Accessories

I received this yesterday and am pleased with what I have seen so far. This is basically a hand grip for using the Doc Johnson Vac-U-Lock line of strap on dildos. If you are not familiar with this line of dildos, I recommend doing some research. They have been around for many years (15 or so if not longer) and are very well regarded and easy to use.The Knuckle Up gives you a new option for play with the Vac-U-Lock dildos. There is a nice selection of dildos available from a 6" average unit to one that measures over a foot long and has girth that only the boldest players will be able to enjoy and appreciate. The 6" and 7" models are pretty common and average sizes. Both would be easily used with the Knuckle Up. Moving to an 8" will give you a bit more of a work-out. The 8" is longer and heavier and changes the balance/weight distribution a good bit. Still effective but more challenging for rigorous play. If you move up to the monster ("Hung") model, it's going to be a lot more of a workout. The weight will be mostly at the end of the dildo and unless you use a second hand, support and guidance will be a challenge. You might feel that way with something as small as the 8" depending on the play involved.The best thing about this is it's a nice option from having to use your Vac-U-Lock dildos ONLY as strap on devices. The Knuckle Up gives you more direct control and coordination as well as different options for additional stimulation with your other hand. For the price it is a nice addition to the toy chest. If you're just getting into the system, you can certainly take your time and enjoy the belts (they make several different models) before adding this.Or, maybe you can decide to start with this instead. Strap on systems have certainly become much more accepted in sex play in recent years, especially among female only lovers. But there is a huge advance in acceptability among the heterosexual community and more couples are exploring different options. The Knuckle Up is a nice way to add a different option to all of the above play.We have now ordered a second one as one of our friends fell in love with the original and we gave it to her as a gift. So much fun and so much more flexible than just holding a dildo or trying to wear a strapon.But it now!!

Arrived with the tip broken off and completely un-useable. Cannot return or get a replacement. Zero help from Doc Johnson.

These were great on all of the Doc Johnson toys as well as my fort troff toys and a much better price

Doc Johnson is by far one of my favorite makers of adult toys out there, it's been around for years, but the Vac-U-Lock takes this brand to a higher level.From beginner to extremely advanced freak, Doc Johnson has something for every level. If you are beginner, I would suggest something down from this.A more experienced user will be able to use this toy safely and pleasurably.The knuckles have a rather larger grip (I'm female with med-lg hands) so I had to just hold it and use it a little before feeling comfortable. I did end up sanding the brass knuckle part because the edges were a bit rough and that helped my hand fit more comfortably as well.Can be used for masturbation or partner play. Very fun for female top, but pick your dong wisely because it's more of a workout than you'd think!Overall:: I would buy it again and I would recommend to anyone looking for something out of the box. (Literally)

After a few uses it will NOT stick to a SINGLE surface. It comes loose and falls over on tile, plastic, and metal. Thought it was a ood replacement at first but nope.

I've wanted a cup that can toys a little further off the wall for a long time, and this is great! Sticks really well to glass and acrylic, pair with a drill bit for adapting your old toys to it and you'll be off to the races.

I received the vibrating plug, charged it for a few hours and it doesn’t work. Very disappointed. I sent an email to customer service but the website returned an error, so I’ll have to call to get this straightened out. Inconvenient. Caution before buying,

I almost always use one of two reciprocating saw's for the Vac-U-Lock attachments... but recently moved into an apartment. If you want to be nice to your neighbors, it's best if you use that super loud thing during the day and this at night.It's really solid, well constructed. Much better than I thought it would be to be honest. That said, not a flaw just something people might not think about... this only works for a few positions. If you go for a while or your partner likes it for a bit, your wrists will be hurting if you do any basic positions. Doggy is great for this one. I'm thinking of buying a second as well for when friends visit.If they read these reviews... please make one like a sword handle. Like your Man Rammer dildo, but with the adapter where the dong is please. That way all the different angles would be covered between the two of those :D

Ma femme l'utilise pour ses dildos avec sa machine sexuelle et elle le trouve vraiment bien

This is a great product. I use it with the love arc bar to use toys with compatible holes in them. This works great and I highly recommend it.

Mayor comodidad para manejar juguetes sexuales

ni la ventosa es buena (probada en 3 superficies) ni tampoco la extracción despues de su uso en el juguete ha sido fácil. No admiten devoluciones en esto, así que dinero perdido.NO LO COMPRES

Works great, great service
