      Reviewed: 28 April 2018 by Craig197231

      Well as always delivered in a plain box by Royal Mail next day delivery.

      I was impressed with the packaging and a little bit apprehensive when seeing the size of the box.

      On opening the box was a little bit surprised at the size of the three interchangeable dildos. The harness is of a very good quality and is both comfortable for both myself and my wife to wear.

      My darling wife couldn’t wait to get it on and try it out. Not being a beginner in the strap-on department but still feeling nervous at the size of these, we started with the smallest of the three. After applying liberal amounts of lube slowly but surely we managed to get it in. With every thrust seeming to go deeper and feeling easier to receive.

      After about 10-15 mins of playing we decided it was time to step up. I decided to skip the middle one and go for the full 10" dildo. Wow what a beast this one was. With lots of lube and bit of gentle persuasion and a gulp, we were in and boy did I know it was in. My wife, however, seemed to be enjoying herself even more with every thrust. After about 10 minutes enough was enough.

      Fast, discreet packaging from LH.

      I’m a total newbie to the world of strap on play. My partner, however, is pretty experienced in self play, so I took the plunge and purchased this kit knowing he’d love the real feel and larger attachments.

      Opening the delivery box, there was the well-displayed Vac-U-Lock kit box. This is a heavy substantial bit of kit! The Vac-U-Lock kit box is strong and perfect for storage. It does picture all the contents on the box, so if discreet storage is required for you it's something to keep in mind.

      I opened the kit box and the top panel contains all the extras, powder, real feel replenish powder, toy cleaner, O-rings et cetera. Underneath the top panel was the three attachments, all wrapped in their own sections. It was clearly packaged with care, which just added to the whole feel.

      Upon toy inspection I cannot express how realistic these are! They feel exactly like real skin. Combined with realistic looks, you are not getting any closer to the real thing. They even adapt to heat during play. They get warm from you and stay warm.

      My partner was amazed too and says they feel exactly like the real thing. So in that sense, the extra expense over other kits just really didn’t compare!

      Really easy to clean and care for, the kit comes with the cleaner and the real-skin powder. They go slightly sticky after washing, so this powder just restores them back to a non sticky feel.

      The harness is fully adjustable and very comfortable. Adjusts around the waist and the legs. And has two removable suspender clips at the back but not the front. The padding across the back provides comfort and support. This harness also has the O-ring clips, so any flared base dildo can be used. You’re not strictly limited to Vac-U-Lock attachments.

      Well worth every penny. Cannot stress enough how amazing the real-feel toys look and feel!

    1. The most versatile set on the market

      Reviewed: 03 November 2017 by strapon_banana, a Straight Married Female

      We are absolutely delighted to be sent the "Doc Johnson Vac-U-Lock Realistic Dildo Advanced Strap On Set" in exchange for an honest review. This looks like a beast of a set and we couldn’t wait to get hands on! First off we mention it every review but it’s always worth mentioning, especially when large strap-on dildos are concerned and that’s how fantastic Lovehoney’s packaging and postal service is. It’s always fast reliable, and most importantly, very discreet.


      The first thing I noticed before even opening the Lovehoney postal box was just how heavy the parcel was! It’s obvious from the start that you're buying a serious piece of kit. Inside the discreet packaging we have a well designed box showing everything included, which is an impressive array of goodies, and thankfully no hideous pornographic images!

      For our money we're getting three dildos (8",9" and a whopping 10"), adjustable harness, Vac-U-Lock harness plug, Vac-U-Lock suction cup plug, 3 differing O-rings, lube, toy cleaner and Vac-U-Lock powder. All these lovely items make up for a truly versatile set with many uses.

      The cocks:

      I must admit, when it comes to sex toys and dildos in particular I’m a bit of a toy snob and I normally avoid anything that isn’t silicone, but keeping an open mind I was pleasantly surprised and impressed by the Ultraskyn dildos. They have a lovely soft velvety feel on the outside but a firmer inner core so your cock will go where you intend it to go. I’d say that the feel these dildos are the closest to lifelike that I have ever come across.

      When looking at sizes, it's worth noting that there is no beginner size. I would pitch these at intermediate and experienced uses only. The two smaller cocks both come with testicles, and the larger 10" one is all shaft.

      The harness:

      The harness is very much a case of don’t judge a book by its cover. I say this because I wasn't expecting anything amazing given the picture on the box. However, as with the cocks, I was pleasantly surprised. Once more, the harness is well made with quality seams and stitching, and very adjustable to accommodate all sizes. The harness includes suspender straps which are removable if you prefer not to have them, and the material is soft and smooth, especially the large pad that wraps around your hips and back.

      Vac-U-Lock plugs:

      Two plugs are included. One is for use with the included harness. This features 4 press-studs, giving it a good stable purchase on your harness, and the other is a suction cup Vac-U-Lock plug for some hands-free play. I tested the suction cup and it attached to our tiled bathroom wall with no problems at all, again increasing the versatility of this set.


      Three rings are included of varying sizes. The O-rings are a great addition to the set as they let you attach any dildo to your harness provided it has a suitable flared base. We tested this with many other dildos in our collection and can confirm it works great! The O-rings can also be used for a sturdier hold on your included dildos as you can use them in conjunction with the harness Vac-U-Lock plug system.

      Lotions and potions:

      Often when companies include lube with sex toys. Generally it’s only a token gesture. But in this case it’s not. Included is a good quality lube and plenty of it inside a 118ml dispenser. It's just as well you're going to need plenty of it with the size of these dildos.

      Also included is some handy toy cleaner also in a 118ml dispenser. I washed the toys with warm soapy water and aloud to dry naturally with no problems. I used the included toy cleaner as a final clean before putting our dildos in the toybox.

      Also included is the Vac-U-Lock Powder, which makes popping dildos on and off the included plugs nice and easy.

      Finally, the last item to mention is the Ultraskyn restore powder. I’ve not used this yet but it is what it is and I’ll be keeping it ready for when the time comes.

      Our experience:

      So getting down to the fun, it is worth noting first that were a female/male relationship and I myself will be wearing the strap-on and my husband will be on the receiving end. As the box states, this is an advanced strap-on set. With a title like that you can make a good assumption that these are dildos will require a certain amount of warm-up before use. With this in mind, I started slowly using my fingers in his anus, working up slowly stretching him further and further until eventually I felt he was ready for the Doc Johnson strap-on.

      The harness went on like an absolute dream and felt great I was starting with the smallest 8" dildo even though it was the smallest. I felt so empowered as a woman I haven’t even used it yet and it was making me very aroused. With my husband bent over and a generous amount of included lube, I slowly slid my strap-on cock inside him I was able to go all the way to the balls and I could tell he was loving every second of it. After a while I was able to increase my rhythmic thrusts inside him and he was making all the good noises. I think he tried to say something about how nice it felt, but the ecstasy of the moment had mostly taken him and I only really heard moans and groans.

      After some time I thought his arse would be relaxed enough and very much ready for something a little bigger. Out comes the 8” cock and in goes the 9” cock! I have to say swapping dicks was so quick easy his anus had barely any time between my dick upgrade and I found the 9” cock slid in with no problem. Again, all good noises from him and I was having a great time! I didn’t think a strap-on dick could be so much fun. I was seriously getting off on the pressure against my clit from the base of the dildo as I thrust deep into his arse!

      In the interests of a full review, it would be only fitting for me to increase my cock size one more time and swap in the monster 10” dick. Again all went perfectly well. I wasn’t able to thrust as hard as before because I was close to my over half’s limits, but still we had lots of fun and I was still able to go fully in him just at a much slower pace. Just one safety notice regarding the 10" cock. It has no flared base, and though unlikely, it is possible the dildo could come loose and, well, get lost where you wouldn’t want a 10” cock getting lost! With this in mind, please ensure the dildo is firmly attached onto the Vac-U-Lock system before starting.


      The price tag is quite high, but if you break it down you're actually getting very good value for money given the amount of goodies inside the box. Go buy this if you're an intermediate/advanced user. For beginner’s I'd recommend something else a little smalle... But then go buy this set when you're ready to move on.

      Versatile kit with many options available. The dildos feel great.
      I'd have preferred the 10" cock to have a base.
      Bottom line
      Great set for intermediate/advanced users.
