He guys, my work experiment continue. So, here u can see the release 1 (left) and release 2 (right) of MC Tank. It's like a "map tank" but it's in ONE pieces of alluminium and it works with XL CE2 cartoms. Rel 1 4.5 ml of juice, Rel 2 about 5.3. After this, i did a new version for Ego/Riva battery. 3.2 ml about of eliquid. Some photos: What do u think about that ?
