The Legend RDA by HCigar, is stainless steel construction with a triple post setup. The big post holes allows thicker gauge wires, slightly over-sized Phillips screws provides easy tightening, and the center post is maintained by a high heat insulator. The deep well helps absorb an ample amount of liquid when doing dual or quad configurations, and the 510 connection is fitted with copper plated contacts. The center shield and top cap are removable and serves as adjustable air flow for different draw in vapor production.
