The harness may work better for people with meatier thighs/hips, and with a female on the receiving end. The harness seemed to lodge itself right on top of my hip bone and dug its way it. Very uncomfortable.
The dildo itself poked my (male) partner so badly he made me stop. He said the material was stiff and sharply dug into his insides, and was quite painful. The seam on the shaft also provided some discomfort for him.

As stated, the PVC material of the dildo was very stiff and poked the insides of my partner. He described it as a sharp stabbing feeling. The shaft of the dildo had a seam that ran down along the edge, and was not only noticeable, but caused additional discomfort.

The straps of the harness were a bit stiff, but it was brand new so that is somewhat expected.

The harness was okay. Even though it fell right on my hip bone, there were pads in other places that made it not entirely terrible.

The dildo itself has a curve to it that does not bend easily, and the tip is very pokey. This is aggravated by how long and thin it is. Pretty sure you could take out an eye with it!!! It also has a seam going down the entire shaft that provided additional discomfort.

May not be best for users with lots of bones sticking out, and nothing for the harness to 'grab' onto.

I suppose it could have worked a lot better with a female on the receiving end. Our experience was certainly not a positive one, but I have hope that the harness can be saved and kept for other toys in the future.
No position seemed to relieve the discomfort completely, but the dildo is curved in such a way that trying another from behind was infinitely more difficult.

We tried this out for Valentine's Day. It had been a topic discussed between the two of us for some time, so we were very enthusiastic about trying it out!!! At first we tried with him bending over the side of the bed and me standing, but the curve of the dildo wasn't exactly meant for that. So we tried flipping him over, and it was slightly better but ultimately he said he wanted to stop. It's still an interest of ours, and he is still very willing to try out other products as he recognizes the material was just not suited for him, and probably won't be a universal truth.
