I don't usually watch vaping vlogs but happened upon Grim Green's latest yesterday and heard something pretty interesting. Apparently, he was sent a Vapresso Target for review and was spotted with it on instagram by a large vendor. The vendor contacted Green and informed him that there had been some testing done by a third party and found that the ceramic coils could be harmful or toxic. He did not reveal the name of the vendor or go into great detail as there is going to be further test done and he's awaiting the final results. I've always been weary of ceramic coils so I'm really interested in how this will all turn out. Anyone else hear about this? The vlog can be seen here and the Vapresso coils come up around the 59 min mark.
