I've had the Baby Prince for a few weeks now, no matter which kind of coil I use (either SMOK or Vaporesso NRG coils) it leaks awfully. I close the vents when I refill, remove the tank when I charge so the liquid doesn't get too hot and leak but no matter what I do it leaks so badly. I've tried wiping all over the o rings before I change the coil so everything is nice and air tight but I get to much liquid coming out of the vents especially now I have the bubble tank on it. I've tried upping the wattage, I'm using a high VG (80%) liquid and nothing seems to help. Has anyone else experienced this and how can I stop it?! I love the tank but the leaking has me reaching for me Riptide instead because I never have issues with that.
