So I recently ordered my first rda, a mutation x v3 from kidney puncher in copper. I went with the mx because I read the deck is easy to build and learn on and I went with copper because I think it's a great color. But I was unaware of the concern in the community from using copper rda's/drip tips. Have any tests been done yet to determine how detrimental it is for you health if at all? Heavy metal poisoning is the last thing I need.
