Ok I just got mine today and I do have to say it taste way better than I thought! My only issue is NO VABOR is there a trick??
Vapor is a function of juice base (Pg or Vg) and the condition of your atomizer, battery, and cartridge. VG gives you the most vapor, PG provides a little more throat hit. Some people say that Pg dries out or irritates their throat. Some Pg liquids don't produce much vapor, especially compared to Vg. Others are a combination of Pg and Vg.
The other part of low vapor is a dry or flooded atomizer. If the atty is getting hot and you have no vapor, the filler in the cart may not be touching the atty bridge. The filler should be even or just a little below the edge of the cart opening and you might see a dent where it contacts the atty.
A flooded atty will gurgle sometimes. You can blow out the atty by holding the open tube side toward a paper towel and blowing through the threaded end. After 5 or 10 seconds of blowing, you will see a drop or two or juice fall out. Insert a good cart and try vaping again. If it was flooded, you should soon have good vapor after puffing a few times.
If you are getting taste and no vapor, try another juice. Drip a couple of drops directly on the bridge and see if taste and vapor increase. If that increases production, then look at your cart, refill it, or try another cart. Sometimes the polyfill filler will harden on the end.
