I bought 2 Vision Cartomizers. I recieved them yesterday and filled the first and let it sit for 30 minutes. Life was good! I filled the second today with a different flavor and it sat for a couple of hours. I pulled out a freshly charged battery and attched the cart AI filled today and trying to pull air through this thing is like trying to suck a golf ball through a garden hose!! Can some one shead some light on what I ca do?
