GAIA RDTA is designed by Brian N(CA,USA) and made by Cthulhu MOD. It is balance RDTA(the balance of cloud and flavor). We designed and made 5 different top caps, and chose the one that bring the best flavor. It comes with adjustable bottom and side airflow, we can choose the best airflow to fit your building. You can choose cloud mode and flavor mode as you like. We try our best to make the top cap shorter to reduce the flavor loss. GAIA RDTA is a small Atty with 2ml capacity, easy refilling as RDA doing(click here), Squank friendly. And it is made by 304 food-grade steel and PEEK insulators.
