Unfortunately, this product failed to live up to my hopes. I had high hopes that one of a limited selection of double-duty dildo harnesses would:

-fit snugly

-stimulate both my partner and I at the same time

-require minimal attention while in use.

I was aware of course, that a strap-on is not a penis, and as a beginner user, it would require some manipulation and there would be a learning curve, but this device required far too much attention to keep in place.

When it first arrived, I strapped it on without the battery packs for the vibe element attached. The waist strap was appropriately adjustable and I was able to get a snug and reasonably comfortable fit. However, the strap that went around the bum was far, far too long. Short of cutting and re-riveting that strap, there was no option to hold it more tightly in place.

Further, the space between the vaginal plug and the base of the dildo was a bit short to maintain vaginal penetration while keeping the dildo in an erect position. These drawbacks caused me to doubt any chance of keeping the vaginal plug in place during active use.

My next goal with the device was to learn how it would move during sex, and how I could move it to maximize my own pleasure. In a range of different positions and completely solo, I lubed it up and attempted to "masturbate" it, finding the angles and thrusts which were most likely to lead to vaginal stimulation.

Eventually I managed to bring myself to orgasm, but it was a difficult road. Still, I learned a lot about how my body could interact with the harness in order to use it to the best of its potential and certainly, I was ready to test it with my partner.

We put batteries in the power packs and quickly found another drawback. The idea of dual controls is a good one but the cords and battery packs were a huge impediment to any sort of active play. Since both battery packs are identical, it was difficult to keep track of which knob controlled which end of the device. In future, I imagine I'll mark them somehow.

The box displays the battery packs as strapped to thighs, however, there are no means to attach a strap and indeed no straps enclosed. Further, if each person keeps a hold of their own controller, partners are closely tethered together, further impeding free movement. If either partner overextends the cord attached to their end of the penetrix, the harness is yanked out of place.

When I penetrated my partner, he was most pleased with the size and pliability of the dildo; this is the only way in which the super-penetrix performed well. Although I still had to use quite a bit of effort to keep the vaginal plug in place (and eventually allowed it to slip out and hang loose), the dildo end is perfect for anal thrusting. It's tapered and quite slender at the tip, flaring slightly at the bottom. Although my partner initially had misgivings about the length, it wasn't long before he was thrusting for more.

The adjustability of the vibration speeds also added a fantastic element. Unfortunately, the fit of the harness was also an impediment to being able to reach around his body and masturbate him; though I was pleased to find that while he lay on his back I could achieve some oral stimulation.

After sex, washing the device was nerve-wracking. There are several layers of material making up the dildo and vaginal plug. Also, there seems to be no sealant other than rivets holding it together. Given that there are electronic elements enclosed, washing had to be done quite carefully. The material which forms the outside of the device is quite porous and I will be sincerely surprised if this product doesn't start falling apart after less than a dozen uses.

All in all, this was a disappointing product which I would rate at 1/5 (for the size and shape of the dildo end).

The Super Penetrix has made its way out of my rotation of toys very thoroughly. Being the only strap-on I owned, I was reluctant to abandon all hope, but after a half-dozen frustrating episodes and an inevitable decline of the vibrators due to their unprotected state while washing, the toy lies abandoned at the bottom of my chest.

The shape and texture of the dildo end remains the only saving feature of this toy, as I hear it reported that it is ideal for those new to anal thrusting. Many of the issues stated in my first review: poor fit, restricted movement, and difficulty washing were merely reinforced by future uses.

While I had retained some hope that it was my inexperience causing problems, it seems that even with considered effort and much experimentation, this is a novelty item at best.
