Hey guys, So before I knew anything about the vapor world I made a grave mistake like most noobs and thought the way to quit smoking is with the blu electronic cigs. I first purchased a starter pak and quickly purchased extra cartos a few days later. My entire blu cig investment is around $70 and regretted the entire experience. I hadn't vaped from the blu pak after getting my mod and kayfun clone then out of pure curiosity I checked to see if the blu cartos would work on my mod. I screwed in the carto and prayed that I could salvage some of my terrible blu investment. I vaped off the blu carto for a bit and am really happy to say they work just fine on my mod. It's not the best flavor but at least my blu experience is not a complete loss.
