Hi I have ordered the Jacvapour VGO2 VV with 400mah and 900mah batteries, also comes with 2ml and 3.5ml Nova clearos. What other tanks/tips fittings would also be suitable? Also any other tips, thoughts, advice would be appreciated, not entirely new to vaping but at the same time am a bit of a novice and I simply want to get the best out of my kit. Has anyone tried these?
