None of the Davides have come with air flow control. The Kanger AFC bases meant for the Protank2 are a direct replacement. I'm thinking of going this way. $15 for the Davide. $5-6 for the AFC base. $21 gets a Davide w/AFC that accepts Kanger BCC and Aspire BDC/BVC heads. This is perhaps a better choice than Anyvape's Peakomizer.
