V4 on the Kroma-R. Gona take all these tips before I show my k@k wicking lol. But none the less super impressed. Versus my Hellvape MD and Berserker Mini, the V4 is just a on another level I still can't understand this that there is so much of clean crisp flavor tasting desert notes that I couldn't get before. Using the VV Superfine MTL coils for now
