I started using a vivid ecig almost three weeks ago. Was a 20 a day smoker for 24 years and haven't had a normal cigarette since I started vaping [smile] I have been reading some of the threads on here and talk of battery life made me realise I should invest in something a bit better. I'm happy with the juices I'm using and they're working really well. I ordered a mini pro tank and it arrived today. The battery is charging and I'm excited to start using it! [grin] My question is, how do I fill it? On the vivid the mouth piece unscrews. Do I just fill through the mouth piece or unscrew the bottom part where the coil sits and fill it from there? Won't it spill back out the mouth piece end? I'm a bit [confused] and really don't want to ruin it! Thank you!
