I received my 4th EVOD today in the mail today from sweet vapes. It has "EVOD BCC" written on the bottom edge, right above the base. Other than that it looks identical to the others that I have. I know that at least my first 2 aren't knock offs because they came with an EVOD kit I got in the legit Kanger packaging. I've never even seen pictures online of them with this on them. Are these new? Or am I missing something
