eglek,
You shouldn't need to puff at the
ecig until you get any vapour, you should get vapor from your first puff. If you are puffing lots and lots then there is chance that you will be overheating your atomizer, and that won't help its lifespan!
The first thing to check is that your battery is lighting up with each puff, also, does each puff cause the atomiser to heat up a little? I've had the case that my battery is lighting up, but it wasn't powering my atomiser because I'd managed to get some fluff jammed in between the contact of the battery and the atomiser...
This may not be the best
thread to ask for help in either, you might want to post in the new members forum. I'm also assuming this question wasn't directly aimed at me either...
