Good friend of mine told me once, and it stood in my mind till now. As much he prefer the real deal, but he would only get clone mods, but not clone RDAs, and the reason is RDA is where ejuice is heat up for us to Vape into our bodies, he would prefer authentic RDA for better quality of material. I had purchased and used many clone products, but since that conversation, i only buy authentic RDAs. Just something for you to think about.
