Here is a tip that I haven't found on other forum sites that would have stoped me from making a couple of bad decisions:
Do not use your automatic e-cig while driving in a car with the windows down; the suction caused from the open window may be enough to activate your e-cig, not enough to light your led light, or produce any real tell tale vapor to let you know whats happening, but it can slowly char-fry your cartridge. It happened to me once when I had my pen style sitting on my lap while driving with the window down a little, and when I got to my destination I picked up my e-cig to find it quite hot; what was once near oderless was no longer oderless, and what once tasted sweet, now tasted worse than a GPC brand ciggarett.
The same problem has accured while trying to use my auto e-cig outside on a real windy day. So to avoid these problems its best to go with a product that offers a manual switch.
