My very first vape, looking on the internet so many different units, liquid's I was unsure where to start then a site referred me to Smoko. The site was easy to use and very and I do mean very informative so I think I had found the one I would try but still having a few questions I used the in site chat to ask my questions which were answered nearly instantly I made my purchase, got my order the very next day and have not looked back, not had a cigarette for a week now and just placed my second order for more vape refills. So if you are not sure what to go for give Smoko a go you will not regret it.
