Like offroad8x6, my B/F bought a kit for me. I always knew i was above average, but never really thought about it, so my b/f said we'll make a clone and you'll see how big it really is. The kit is easy enough to understand and to make the clone is easy, b/f kept playing with my nipples to keep me has hard as possible. But like Italiano34 there is not enough liquid to fill the mold completely, I'm 8.5 soft, and 10.5 hard. My clone was about 2" short as well. I too sent an email and then a letter to the company and never heard back from them. So if you can afford to blow some cash on a clone kit, I would suggest buying two kits if your really large. Stay away from castawilly if you want good customer service.
