I got this as a small surprise for my wife. Just like many other reviews, staying hard without any "help" was the most difficult part of the project. I followed all the instructions to a T; therefore, had no difficulty with the molding. I'd recommend a cock ring to help in staying hard, but even using a ring I could only keep 75-80% hardness.
The only problem with both the mold and the latex was that due to my size and a bit of a leak from tube to body, I didn't have enough of the mold to fill the tube and surround my penis. If a full mold of my penis was made, there would have not been enough latex as there was JUST enough latex after scraping the containers dry.
I waited 48 hours prior to removing the latex from the mold. The detail was amazing! For the exception of being a bit shorter and a different colour, a person would have a very difficult time telling the difference between the real and the replica. My wife's reaction: "This clone a Willy is insane ! Looks exactly like yours. I am flaberghasted". We have yet to try it out; however visually we are both very impressed.
For guys who may have size anxiety, this definitely gives you a new perspective when up close and personal with your replica. The view from above that we are all use to definitely doesn't do us justice in judging our on equipment. I'm definitely a lot more accepting of what I was born with now. I now understand why my wife often has difficulty going down on me, why I receive the odd teeth scraping on my shaft, and deep throating is still a task she hasn't succeeded at.
Overall definitely happy with the results. The package was missing the included thermometer. Pinkcherry was immediately willing to return the item but I just bought a thermometer.
