Black note is great, but it’s a give and take. As a smoker with a small e-cig this was great for transition (Which is what I think Black note intended) but it wasn’t long before I upgraded my device and I find that 50/50 vg/pg mix gives me tons of spit back and weak flavor production. After trying MaxVG or 100% VG juices I just can’t justify getting more Black note. If I could get an 80%+ VG version I would keep Black note stocked all the time but until then it’s just not for me. Since these are all just device compatibility and personal preference issues though I still say 4/5.
