Upon refilling my carts that came with my e-cig several times, I noticed the fill beginning to pull out of each cart a little each time I removed one from the atty. Does this mean it's time for me to get new carts, or can they still be used? The fill is still in the cart, it's just getting pulled out a little. It's more... What's the word?.. Seperated, maybe? Yeah. More seperated than they were than when I just purchased them. The carts will still hold e-liquid fine. I was told by the clerk at my tobacco store that the carts can be reused as much as you want to reuse them, but I'm not sure if she knew what she was talking about. Can anyone clear this up for me? It would be greatly appreciated
