We have discovered a discrepancy in our latest batch of Acekard 2i's. After a couple emails from our customers, we contacted our current supplier and he admitted to sending us a mixed batch of authentic and counterfeit Acekard 2i's. Please note, we have been using this supplier since the last debacle in early 2010, and up to now he had been consistent. Please understand, as a retailer we cannot check the codes - as they do come up as "fake" if checked more than once - but we do check for contact issues and randomly update the 2i's with the latest firmware. We have been able to update them consistently and the HW id comes up as: 8181. We have contacted Acekard. They claim that all codes are unique. We have attempted to order from Acekard directly, in order to avoid issues like this, but they refuse and we have to order from outside suppliers. To any customer who suspects there is an issue with the legitimacy of your cart, please contact us immediately. En route, we have a new batch of Acekard 2i's that are confirmed legitimate from a trusted partner. If anyone needs a replacement as soon as possible, we are checking codes and updating them with the latest patch. Please note - if you choose this option, the code will have already been checked once, and you will get the counterfeit message on Acekard's website should you feel you need to check it again. To all customers who have made orders from 8/30 and on, we will also be checking the codes before we ship them out. We apologize to all customers for the inconvenience and are committed to resolving this issue. You do not have pay to send the cartridge back. Please contact us through email (firstname.lastname@example.org) or open a support ticket http://www.realhotstuff.com/ticket_create.php to resolve this issue. Feel free to PM me if you like. - RHS *There is one discrepancy we noticed: When you peel back the authenticity sticker ( the silver layer), if there is still a holographic effect left on the surface of the numbers, the cartridge is most likely fake.
