I've had my mini nautilus for a solid year now. It has been flawless except for recent months. I notice a lot of gurgling when I cape that I never used to get. I've gone through all the variables like changing juices and pg/VG ratios tightening loosening replacing coils ,cleaning. My only though left is the rubber rings are just worn and not able to create the same seal? It doesn't always spit but again it used to run flawless. I also remember getting more vapor. The only other thing I could think of was aspire changing to cotton in the bvc. Anyone else experience this? Anyone else use a tank for this long? Haha
