I've spent about $500 and i new to this (about one month) looking for the "holy grail" of e cigs, first i started with finiti and blu cigs from walgreens 
and then my 7s hybrid kit $100 
i'm happy with my 7s but too much money, and then my DIY e juice kit from MFS, and happy with this guys from MFS, great service and i think they have great suppliers too, almost the same suppliers wizardlabs use. But now i think i found my own "holy grail" in Halo cigs i have my halo triton tank and order again a 30ml vodoo e juice, man what's inside this bottle! I should begin with those guys before spent too much money in my "trial and error". I use my halo tanks exclusively for their juices, no DIY on that tanks, i used my 7s cartos for my experiments. I'm not saying that 7s are bad, their great too but not as good as Halo, Guys keep going and congrats for your products and for giving ex smokers like me and thousand more a great vaping experience, i'm on your list.
