Hello , i am in the unpleasant position to report to you that , after buying an ASPIRE NAUTILUS MINI TANK from an EBAY seller , I found out that it was fake. Not only the packaging was as bad as you exactly describe it to your "watch out" web page , but the air intake holes series were counter placed , opositte from the correct direction. I had to turn the ring to the left to increase the airflow and not to the right , as it should be. The airflow was very little even at the full open position and the BVC coils were counterfeit also with very bad performance.
The funny thing is that i run trough the authenticity verification procedure and it turned out that the product had been genuine !!!
Take steps as it seems that fakers have found a way to over come your verification procedure , or have found out the algorithms that you use in your codes or you have industrial espionage problems...
Thanks for your fine products and good luck.
