My second most favorite mtl atomizer -- which first one is ofcourse expromizer v3 :) Time to time, for the sake of good old days, i still give it a try. It has great flavor as v3 but not easy to use as it.
The deck of eXpromizer v2.1 is designed simply and effectively. For the coils two 1 mm holes are available - alternatively the wire can also be attached directly to the screws. An eye-catcher is the innovative liquid control. With an ring (similar to the AFC rings) on the coiling base the juice flow can be regulated. Several holes on the round metal influence the flow. The practical collector tank collects the excessed liquid and thus prevents leakage of liquids.
A new feature of version 2.1 is the topfill function. Simple and clean filling is therefore possible without any problems.
