They can't help but feel cheated since they can't even ascertain the quality of the product that they are buying. They don't like being cheated at all.
But as if being cheated isn't bad enough, it becomes worse once one of their slaves uses the memory fragments and the memory fragment disappears without a trace.
Once the memory fragment is used, it is gone forever. They will have to buy another one for their other slaves, which means they will have to be cheated again and again.
And in case the memory fragment is faulty, they can't return it or use it as proof of being cheated. So once a memory fragment is used, they are stuck with it forever.
All of these difficulties made them determined to reach the legendary rank soon. Once they reach that stage, not only will they be able to determine the quality of a memory fragment without using it, but they will also be able to copy the memory fragments and sell them to recoup their loss.
