I just got into RDAs a few months back--- and did not want to drop a ton of $$$ on a new hobby right off the bat that I may not be into or may have a hard time at. So via FT and Ebay I purchased 3 clones, and I have to say that I was pleased. One was junk, burned the crap out of my lips. One is so so................ and the third a Vertex clone is a champ. Now that I have my feet somewhat under me and want to continue with RDAs.............. I will not be as scared to drop good money on an authentic one in the future
