i have tried contacting SI for the past week about the 20 XL cartomizers that i recieced last week that are all bunk. every single one if them will not absorb an juice at all. and if i poke the filler with a needle a few time, the juice runs straight out thru the bottom. i have wasted alot of juice trying to get these things to work. i know there is no warranty on cartomizers, but if i would have known about the XLs being bunk i would have got the regular ones. is there anything SI can do? im dissappointed considering that was my months supple of cartomizers.
