Hi Turkish, Welcome to the ECF. Most of us began very similar to you. I personally began vaping with a single automatic battery kit with sleeve cartridges. I remember refilling one with my first liquid purchase, which by the way was almost three months+ after I started vaping..... seven drops from empty to full...... I had just the week before found about the ECF and was swimming in information.... My next kit was a 510 with two manual batteries and big cartriges compared to my little ones on my first PV. I was happy with this kit for about a month. Thats when I finallly knew vaping was for me so I Invested in a big battery kit eGo clone. The eGo was my go-to device for almost a year.Now over a year later the eGo kit still travels everywhere with me but, I have treated myself to a variable voltage mod and since mid January the eGo hasn't seen much robust use. But in the end I still have all my original equipment and it all still works. The prefect one is the one that keeps you away from cigaretts, everything past that is all just bonus material. Good Luck. Happy Vaping.
