That's good to know. I got mine from sweet-vapes and as far as I know they only sell authentic stuff, or at least when they say it is it really is. It had the checker but I didn't run the code, maybe I will now.
This still gives me hope that I may just have gotten two bad coils. I am interested in the sub tank and also the lemo. I just need to back off the spending for a while, the rDNA wasn't cheap!
