This kit is definitely a great idea and the result is fabulous if you get it right. The secret as you are told in the instructions is to get the moulding of your penis right and this will happen if you follow the instructions given with the kit exactly. The most important thing to bear in mind is that the moulding paste sets very quickly and you can be caught out by this so easily. I found it best to have the warm water ready in a measuring jug and the dry powder out of it's packet in a bowl for ease of mixing the two together quickly. Get yourself as hard as you can and then mix, stir and pour without delay.
