Wow, this thread is a real eye opener about how people view dice rolling in games. I would have thought people would prefer untumbled dice. Im... shocked. I own 3 sets and I love them, I know players that roll with dice that turn up 20 way too often to be coincidence, I make them use these and it gets rid of that problem very quickly. The ones I own are much more random than any other die sets I currently have. The only other better dice rolling would be a random number gen on a computer (yes I am aware it's not "random" as it is based off an internal oscilation device but it's random enough for a human not to know how to manipulate assuming you arent a coder)
