My experience a mixed bag. Used them for gold a couple times and they were fine. Recently hired their raiding service for a quick ToT clear. Fine and quick on that. But they also accepted an order for a Siege of Orgrimmar clear and 8 days later, despite assurances they would start, haven't lifted a finger. 3 days ago they said they would start it in 2 days. They lied about that. Will give them one more day to begin, but after thatI will not deal with them again. For me one lie from a service provider is one lie too many. It will probably take me awhile to get my money back.
PS they refunded my money, but it would seem the site has been shut down completely.
