I AM SO FRUSTRATED!!! 
I started with a Kgo about a month ago. Everything went really great for about 2 weeks. I was getting frustrated with flavor and also having to drip into carto all the time. I decided to pick up a infinity pro with a 3ML tank and some pre punched boge cartos. I absolutely love the ipro it work great. My problem lies with getting a constant pleasant flavor from my juice. I don't know if its the way I fill the carto or tank. I had this same problem on my Kgo also however.
Basically I can be vaping and everything tastes great. Ill set my PV down for an hour or 2 and when I take another drag I run into a variety of problems. Either it tastes harsh and burns a little, or its seems flooded and its hard to take a drag and also tastes bad. Basically it just doesn't taste "right". I feel like almost every time I vape I really only enjoy about 50% of the puffs. I don't know what I am doing wrong.
Right now my process with tank filling is I fill up the carto first, then I fill up the tank. I always leave my pv standing up on my desk or what not with the tank up. I rarely set it on its side. I don't know if laying it on its side will effect anything so I always leave it standing up. I am using 20%VG 80%PG juices mostly. Someone please help me understand what I am doing wrong. I love vaping and need to figure out what I am doing wrong.
