Hello and thank you for reading. Hopefully I can explain it without confusion. I'm pretty new to vaping so bear with me if I get the "lingo" wrong. First I should say that I have a Smok QBox with a TFV8 Baby Tank. The max watts is 50 and i'm using V8 Baby-Q2 coils (0.4) currently. Mine came with 2 V8-Baby M2 (0.25) coils and I had an issue with both. I went to the local shop that I purchased my Mod and bought replacement coils (Q2) in a 5 pack. The guy at the shop replaced the first one for me and I watched diligently. It lasted for 3-4 days. I replaced it and took the steps exactly as he showed me... Primed it by putting juice on the side holes, dry drags, let it sit for a few minutes, then hit it. Instantly it tasted burnt. So I thought I did something wrong, tried again with the other 4 coils! These times I tried a few different things.. Poking holes in the cotton, letting it sit for an hour, doing dry hits and then blowing out excess juice, starting with a low watt and gradually going up... None of these things worked. I took apart one of the coils and NONE of the cotton had any burn marks at all but still tasted burnt. I've also tried using two different brands of e-juice. I'm really not sure what I'm doing wrong... Please let me know what you think it might be!
