I got an order of 510 cartos. The first one I opened was missing the two air holes so i couldn't use it. No big deal, I had 9 more. The next seemed to work fine but had a funny taste to it. I figured it was the new e-liquid I got with the order. Then I tried a different flavor in them that I previously used in regular carts. They tasted aweful. It's hard to explain, but it kinda tasted like the wick was burning and not the liquid. Very little vapor if any was being produced. I used up the next three out of the pack thinking I just got a bum carto but they were all like this. I also tried different methods of filling them on each (condom method, direct drip through the battery end, popping off the silicone end). I also let them sit for hours to soak up the juice. Has anyone else had taste issues with cartos or am I doing something wrong?
