Hey guys. I've been lurking around these forums for a while now, and finally pulled the trigger on a 510 kit. I'm proud to say that I've been smoke free for almost a month now. I then convinced my girlfriend to make the change too. We ordered her a black 510 3 piece kit. However, there seems to be a problem. Her cartridges leak like crazy! They fit VERY loosely on to her atomizer. For comparison, my white carts fit nice and snug on my white atomizers AND on her black atomizers. But, as mentioned, her black carts fit extremely loose. I can even notice a very slight difference in size between the black and white carts when comparing them side by side. I'm not getting any cooperation from the vendor I purchased from, so I was hoping that somebody may be able to offer us some sort of a solution. Thanks so much in advance.
