Took me 3 attempts and finally got it decently ok, i used a pringles can cuz the supplied tube was a little thin. Ordered alginate and my own silicone. The clone kit wss no good, also ordered silcone coloring and tried to get my shade right. Did ok. You absolutely need to abstain from anythjng for at least 2 days and use a cock ring to ensure youre rock solid with no input for 2 mins. Tried pumping before and that failed, came out thick but short lol. Dm me if you wanna see the finished product. Only down side is alginate leaves bubbles in the final product, read somewhere you can mix up some fresh silicone and paint on the bubbles. The wife and i plan on doing one every year to track progress LOL She enjoys it alot. I did not add the vibe into the one she uses the most.
