Hey all, I bought my SS about a year and a half ago from a local smoke shop. I just got through my original batch of cartos and so went to the SS website, got some new hendu cartos and a Pitbull battery (so pretty!). These new cartos seem to be sooo different from the ones I got a while ago. Seems like the air holes line up better with the ridges in the battery - giving a much more airy draw. Even if I cover the holes with my fingers, I can't seem to get the vapor production that my old ones will give me. I've confirmed it's the new cartos and not the new battery since the carto is still airy on the old batteries. Also, I'm getting a metallic flavor from the first carto in my 5 pack, could just be a fluke though - popped open a second one and am hoping it won't give me the same flavor over time.. maybe these new ones start to taste metallic when they run dry? Is there any way I can get my hands on cartos like the first batch I got? Is it because I bought the steel cartos and not the white ones that it's so different? Thanks in advance for any advice! Update: The new carto (#2) that I just opened up a couple hours ago is starting to taste metallic now too.. No e-juice, no covering air holes with my fingers. Did I get a bad batch???
