For a year and a half of vaping I have only tried Green Smoke, Blu cigs, and Logic (all high strength). I've never tried any of the e-liquid ones. I have heard liquid is generally better quality than cartridges and can save you alot more money. Right now I pay $20 every 4 days for 5 of the Logic cartridges or $15 for Green Smoke cartridges (Green seems to be going higher and higher in cost). They're both good quality but they don't seem to last me more than 24 hours. I'd like to start e-liquid. Any recommendations for a starter kit and is there anything I need to be wary of when choosing one? Any bad experiences with products you have purchased from tobacco shops? Thanks.
