Hi, I just got my new Ce2's. I am frustrated however. Here are the stats: Royal Smokers Ce2-R4for 808 XL 5v PT Various Juices I filled the carto...the XL take about 1.5ml. Started vaping. After about 5 vapes on PT start to get a chemical, acrid taste that burns the throat (like when a regular carto becomes dry). I go to fill the carto again but it still has juice in it and is still producing vapor. Those first 5 hits are amazing, but I'm frustrated with the filling/acrid taste. If I slow down between hits, it does get a little better and I can get about 8 good hits if I wait about 1-2 minutes between hits. I did a dry burn on one first and it didn't improve over the non dry burn one. Anyone experience this? HELP?
