I think these two points sum up a lot of the frustration with tp Varina since both are true! Without dry burning it is a pita to assess the presence of hotspots/legs etc. If you don't and problems ensue then there is always the possibility juice is being overheated etc as temp is increased to get a decent vape! Rocks and hard places.
So I think there is a real chance that these issues will turn a lot of people off tp before it really gets off the ground. That is a shame but the fact is that to get it to work often does require some thought and some fiddling around. It's not a plud-and-play activity yet!
Yes tinkering is a must. I'm still constantly getting hot spots and sending my temp readings all kinds of whacky. So I finally had enough of putting everything together and then testing, now I just build, then drip drops of juice to identify if there is going to be an issue before I go through the hassle of wicking and what not to then find an issue.
