Well, I'm going to try to write a thorough and honest review as I see it so far.
The method he is selling is unique. The script is simple, but seems stable and reliable. The method has no randoms, and I seriously doubt its' ban rate is high.
Now onto the topic of money. The script does indeed make 1m/hr at normal prices, but it's not quite possible (at least not realistically so) to buy/sell at normal prices. The item produced does seem quite hard to sell, but Bigbutt warned me that it might take overnight to sell. So, I will finish my conclusion of this tomorrow.
Conclusion atm:
Script seems clean and stable. The method is unique, but so far, buying and selling the objects seems a little bit difficult.
