I ordered a 10 pack of the GreenWorld cartomisers. They are fine but what I didn't realize is that the carts do not have air holes. The only way to get them to work is to not screw them on tightly. I don't care for this. Do the GreenCig batteries (the G300 and G400) have air holes on the battery? Also, does the G400 have the 3 second cutoff like the 300? I'm not sure if that would bother me. Thank you.
