I just got a pack of 5 Cool Carts and have noticed that I am going through this pack very very fast. Almost 3x as fast as I would normally go through one. It typically takes me 1-2 days per Cartomizer, and I have gone through 3 since yesterday when I started this pack. I am not vaping any more then I usually do, it just seems like after 2-3 vapes it tastes burnt already. Could this be something with this pack or could it be something with my battery?
