Previous Review: If there were a neutral review option I would go with that. He traded me a csgo gun as alternate payment, I agreed to give him one key back as change. Upon completing the trade I realized that the red gun in his inventory was not the one I just traded for. He insisted that the one he traded me was of equal value, though checking the market showed it to be worth $2 less. He refused to reverse the trade or swap the items and said he had to go. He did refer to the proper item when discussing the trade but due to the similarity of the items in both approximate value, name, and appearance combined with my low familiarity with the game made it an understandable mistake on my part and it would have simply been the nice thing to do to reverse the trade.
