I am fairly new to vaping, and so far I have only tried the Smoketech Cartomizers. At first (And through a few fills; Both tank their dual coil tank cartomizers and regular dual coil cartomizers) they hit great. However, after a few fills or the next day, the hole begins to close up. I've tried using the end of a paper clip and etc. to reopen the hole, but it does not hit the same. Is this normal, or does this also happen with Boge and Kanger cartomizers ? I really like tanks, but hate dealing with these cartomizers because it happens everytime no matter how much I baby them. Is there such a thing as a tank atomizer that anyone could suggest ?
