Thanks for the fast reply

I've tried binning the juice and loading some more in after priming the same coil (just in case) and pulling without the fire button. More bubbles come up and it's pretty much 9/10 every 3rd hit is just 70% dry and 30% vape. It's awful.... I've tried from about 35w, each hit being 2 seconds long and I can't really taste any flavour until about 45w. From there, that's where the problem occurs the most.
Again.. it's always on the 3rd hit. I must've left it about an hour while cleaning to let the cotton soak up the juice but it's just not working the way it should. I don't think it's the coil that's the problem either if I didn't say that already because this isn't the only coil I've had the problem with. Every good hit now tastes 50% flavour and 50% musky. I've also tried on the batteries being somewhat around the 1-5% mark where I can't see anything on the LED screen and even fully charged where I've left it overnight and vaped when I woke up. Again it's always the 3rd hit. I just don't know what to do anymore. Building up from a low wattage and increasing the watts every 5-10 hits doesn't really help. I extremely appreciate the fast response and trying to help me by the way!
