I have several of these DID's but from the classy's and there the Kir fanis tanks , i do have the original stainless ones also but like the clear tanks. Eventually MM Vapors is coming out with DID 22 that reportedly is to have a 5ml capacity which i will purchase when the time comes.
Simple and easy to setup.
Recent purchase was the AGA-T+ that came with glass type and plastic type tanks and i do not like as its tank gaskets impart a flavor to my
e-liquid cause they make contact with each other unlike the real DID gasket setup which does not touch the
e-liquid but i had to try it for the price . I no longer use it or the previous Limited AGA-W version from Europe .
