The Mutation XS is the newest RDA from Indulgence incorporating the popular trends and adding a few extras. It is very small, for a low profile look, but dont be fooled, this atomizer hits surprisingly hard. It also has an extreme amount of adjustable air-flow options, making it compatible with almost any build. The Mutation XS features upgraded diamond airflow holes to induce vapor swirling, also Indulgence added a bottom airflow feature which creates amazing and precise flavor. The Mutation XS atomizer's deck is made out of 100% 304 grade stainless steel. The deck of the RDA features a uni-deck meaning that the negative posts are milled into the deck for maximum conductivity and rigidity. The 4 post design with huge post holes and upgraded phillips head screws allows for various amounts of crazy builds.
