I actually have found the Ruyan V8 ecig mentioned here on EFC way back in 2008. Will be digging further later on tonight.
I know this doesn't interest most people on this forum, but if the Ruyan V8 was introduced to the US market before the FDA 2007 grandfather date (is it still Feb 15, 2007 ???), that means 801 pen style ecig, which is still being made and sold from china, would be legal to import and sell within the USA, no? That's assuming that the 801 really is the same thing as the Ruyan V8.
I know, y'all are probably thinking, but who cares!?

But as a person who still uses pen style ecigs (but I have never used an 801 specifically), it matters to me given I can still buy them from China if I wanted to. At lest as of right now.
Maybe we'll see a resurgence of improved 801 ecig like we saw a resurgence of improved MTL tanks.
