I've been getting so frustrated with all of the filling, topping off, leaking and rotating the cartos, I went ahead and ordered an Ego-T. I'm hoping that will be more user-friendly.
The website I bought the 808 cartos from didn't specify LR or SR, but I'm going to assume these are LR. It takes only 3 good pulls on them to make them so hot I can't even touch them. This tends to happen more on my extra long manual battery.
Didn't you say in another thread that you're vaping almost pure VG? That could be the cause of this. The stuff is like syrup. Pg is much thinner and works much better, though less vapor. But it allows for more flavor.
