So my sister-in-law just got her orchid v6. I haven't built on it yet, i'm looking for some starting advise. Where should i start ? She currently uses a protank 2, with 2.1 ohm coils. She likes the vape with that. I'm just not sure where to start. Also are there any building issues ? As far as leaking wick placement etc... what size coils work best... Just lloking for some advice here.
