I bought what is supposed to be an authentic Kraken but I am beginning to have my doubts. How can I tell? The device has USA serial number 2597 on the insulator post. The bottom of the deck is inscribed with the Vicious Ant logo and "1.1" No idea what the 1.1 is? It came in what appears to be a genuine Vicious Ant box. The machining is very good as is the glass. The positive & negative screws are phillips heads. The 2 wick holes use allen heads. I can submit images if that helps.
