Hello,
I've received my 510 in the mail recently and loving it, but I have an issue with it. It works great when the cartridge is full with juice, but when there is about 3/5 of juice left the vapor production is very little or none at all. I popped off the cartridge and it's still moist with juice. Anyone else experience this? I have some cartomizers ordered so this issue will be resolved, but I felt like this was a question worth asking.
