      Reviewed: 19 December 2016 by mr&mrsajcm

      Great service and delivery from Lovehoney on this.

      Had it delivered to work and no one questioned the big plain brown box.

      Overall a great product, took us a few attempts to figure out the straps, but got there in the end!

      Looks great on the wife and also fits me relatively comfortably too.

    1. What a tool

      Reviewed: 11 February 2015 by Mr lucky, a Straight Married Male

      If new to strap-on on fun, this is going to be your best buy for value for money.

      You may start off small, but if you are like like me, you may find yourself wanting to try new-sized dildos. This has to best, as the Vac-U-Lock attachments all fit this peace of kit, so you have got just one harness. That's just great.

      Must say, had a few years now and still in tip-top condition.

    1. Does what it says on the tin

      Reviewed: 10 November 2013 by Labyrinth, a Straight Going Steady Female

      The Doc Johnson range of strap-on products is so diverse. If you want to be able to mix up your experiences, then this harness is definitely the one to go for.

      It is comfortable and will fit people of all shapes and sizes, is easily adjustable and will not weigh you down. It is crotchless so both men and women could wear it, leaving access for other fun things!

      No more to say really, other than I enjoy wearing this product :)

      Crotchless, comfortable to wear, and a diverse range of products.
      Straps can loosen with heavier toys.
      Bottom line
      Great buy.

    1. A very effective dildo harness for strap-on

      Reviewed: 07 October 2010 by Purpleplumhead, a Straight Married Male

      This novel arrangement comprises a lightweight harness secured around the waist with simple to use straps and buckles in conjunction with a plug attached by press studs onto which the dildo can be attached. The item is unobtrusive in use and has the added feature of a split crotch allowing penetration of both vagina and anus whilst being worn.

      The most important feature in use is that the dildo is kept securely in place hard up against the pubic area giving good control of in and out movement during fucking.

      Whilst my wife and I are satisfied just using the harness with an 8" dildo with balls, the harness will accommodate the whole variety of Vac-U-Lock attachments to suit individual preferences.

      The large thick dildo that my wife uses is not lightweight but the harness stays securely in place allowing her to control perfectly the motion of the dildo in and out of my anus. This provides us with a simple, unobtrusive and satisfying way of enjoying anal sex with a strap-on dildo.

    2. Overall Rating:
      10 out of 10 stars
      Simplicity, material quality, stays in place. Accommodates a choice of Vac-U-Lock dildos.
      Bottom line
      A quality strap-on dildo harness for anal sex.

    1. Made her evening

      Reviewed: 17 July 2016 by asb, a Straight Engaged Male

      I love seeing my GF filled up and she loves the feeling. The reason why we now have a range of very big dildos.

      One of these huge dildos is the Vac-U-Lock Doc Johnson Hung. We have used this dildo in many different ways from me holding it, her riding it for me and even on our Blue Balls Fuck Machine. However, I have always wished I could actually f*** her with it, and now I can.

      The suction that holds the dildo is amazing. Not once did it come loose, even going hard.

      The other good detail, as I am a man, was the hole built in to allow my cock and balls to not be crushed wearing it. This also allowed me to penetrate her when I felt like it instead of the dildo which added to her orgasm.

      Only annoying thing was maybe the straps could do with being a bit of a better quality, but wasn't actually a problem.
