I could too. Especially considering the DNA 75C board was sold before that date and that is ALL I still use. Plus, I now have four HCigar VT 75D mods that use that board. Also all the DNA boards prior to the 75C are also grandfathered in and I >THINK< they also did some wizardry to get the 250C covered as well. All that combined with how they have been working with the FDA should mean that as a company they should be relatively OK. This means mods like the Jac mods, the HCigar mods, the LostVapes mods, and others that have been and still use these boards should be good as well. Same goes for the Yihi boards, and the mods that use them, that were out prior to this date.
This may kill the Gene boards and mods that use it though. It will also impact a LOT of Smok mods, Aspire mods, and other companies that are producing new boards for their mods. Which is really sad considering the improvements made in this time that probably make them actually safer.
The real question is how will this impact tanks and RDA's? I mean if you think about it they are all pretty much the same as what has been out since the beginning. I think they could all argue "Substantial Equivalence". I am not sure if this would fly or not, but really they are all a metal housing with a clamping system of some sort to hold coils, wick and liquid. There are really only two kinds of these. Those that allow consumer built coils and those that require factory built coils. Even if they consider RDA and RTA different, both types have been in use nearly since the beginning.
