I took a bit of a leap of faith when I ordered this set, as I had never purchased from Skullsplitter before. The shipping was lost or delayed or something and I contacted customer support. They immediately shipped out another set and did everything to make sure I got my dice. I actually ended up eventually receiving both sets, but that's a different story. The dice themselves are very nice and have a great weight for rolling. I haven't tested them in any way, but they appear to have a good solid random showing when I've used them in game. All in all, I was thoroughly impressed with the quality, customer service, and humor in all correspondence! I highly recommend the company and the products!
