Hello, I would like to express my disappointment that diamonds can only be used 2 times per day in the machine when this was not stated in the news, on the item description, or in the conversation shown after Using the item. I inserted only 5 diamonds, twice, and attempted a third time before I was presented with an error message saying it could only be done twice per day. Given that the item only lasts for 3 days, that was a nasty little surprise.
