The Helios RDA is a great rebuildable dripping atomizer for advanced vapers. This particular atomizer allows for single, dual, and quad coils due to a double hole positive post and double ground posts. While you can build a single coil on this atomizer, it's really meant to be built with a minimum of two coils because of the location of the air inlets. The outer shell has adjustable airflow with a control ring to tailor your vape to your exact preference. Center pin is machined from copper on this RDA.
Please Note: This product does NOT include wire or wick for building coils, these items will have to be purchased separately in order to use this product. We highly recommend Vapowire Kanthal A1 resistance wire combined with Ekowool or Organic Cotton for this atomizer.
**This item is a clone of a very popular rebuildable dripping atomizer. If you call saying you got a knock-off, we're going to have to agree with you because it's clearly stated here.
