Kennedy Clones RDA Not Safe?

Hi there,

So I've read online that Kennedy clones are being made with copper that contains lead. Is this true or a myth. I'm debating on buying a Kennedy Clone to see if I like it before buying an authentic but the talks about lead in the clones have me frightened off. Also it's hard to drop $120+ CAD on an RDA. Anyone out there that have bought clones and experienced issues or becoming sick? Thanks
