I have been vaping on my Provari 2.5 models for years with a genesis style generic Atomizer on top. It's been so long I cant remember what they were called when I bought them. Something with T2 in the name. I had been happy with my set ups for I think around 3 years. I stopped paying attention to anything new because I had what I needed. I got sick of rebuilding though and started wanting to just smoke. I didn't but I had been wanting to for about 3 months. Last week my 22 year old son told me he wanted the Smok Alien because his friend had one and he loved it. So I started researching it and ended up ordering the Smok Procolor kits for both of us. OMG what I have been missing!!! I never thought about doing a direct lung inhale because I'm a 40 year old mom of three. It seems to look like something the young kids do to me. Well I am too now! I feel silly but its so fulfilling. I was using 28 mg liquid but had to use 3mg as my son told me I would need to. I'm so happy I did! I will still never smoke again. And these coils are so easily swapped out that I will never have to rebuild again. Yayyyyy. You guys are the only people who can appreciate something like this so I just had to share it here. And now I have enough 100 mg Nicotine for DIY to last for ten years using 3% rather then 28%. I never do anything part way so I got myself 2 more Smok Procolors and now I have a back up for my back up again. So Happy!!
