I started out with an eluma cig, pre filled carts was great but the batt life and refills we not what I was looking for. After that in researched and decided to go with 510 later bought the ego 650mah set I am buying e juice from ######, 60/40 pg vg. All of a sudden, I can't get any vapor, taste, or throat hit! I don't get it ..... Different liquids, a ttys, batteries, nothing makes a difference. Only by hitting the a tty can I taste or feel anything. If i use a tip or cart nothing works, so i dd hitting the atty, Help please... It has been several months since I had an analog but I'm thinking if I can't figure it out..... I may backslide.
