I just got my huge shippment in from e-cig (165 carts) and I'm totaly irritated. They were working fine for a bit but then I started getting a funny taste. I took the cart out but didn't see anything wrong at first, finaly it started tasting so bad that I couldn't even think about inhaling so I took it apart agin and the metal portion of the atomizer was covered in the fibers from the core of the cart, the core was kind of hollowed out in the middle as if the center had been burned out or something, anyway I cleaned it out with a pair of hemos and put a smart fixx cart in and its working great again. Has anyone else had this problem with the e-cig carts or other brands of carts? If this is a cronic problem with these carts I really don't feel safe using them. I guess I can always extract the juice from them and use it to fill better brand carts if this is an ongoing issue. I also notice that thier cores seem to have more stray hairs sticky out the end that have to be trimmed off before inserting into the atomizer, oh well I guess ya get what you pay for. I was just really hoping that these would work out as I smoke a minimum of three carts a day and even at 9.95 for 5 I just can't justify the expense. Hopifuly this buying juice and refilling thing will work out. Also if the e-puffer carts that I ordered are high quality, they said they'd sell be 100+ boxed at 5.95 each. Thats a large initial investment but it beats 9.95 a box for sure. I wonder what thye'd sell me 100+ bottles of juice for? I think I'm going to have to buy a fridge and stick it in my basement just to house all the juce carts and snus I'm buying. BTW does anyone know how long juice is good for in the fridge? soemtimes I feel like I'm stocking up for the end of the world, or at least the end of legal e-smoking. and going broke in the process
