hi & wecome, I smoked for 30+ years, much of it on rollies, stopped as soon as I started vaping. (had tried the cig-a-likes, not great, went back to cigs after 5 hours) I've not used a VW device so can't offer any help there. I use a VV device. With an iClear30 fitted with a 1.8ohm coil, I have my voltage set to 4.2, but it's all down to what tastes right to you. Different juices, same hardware, different volts or watts. Good luck with your kit when it arrives. When you fill the tank for the first time, give it a few minutes to soak the wicks & have a few draws on it without pressing the button.
