Well , what i noticed is that there is a lot of air with the auto draw , its kind of like in and out , might be just air at first , then some vape , then more air, and so forth. So it's kind of inconsistent basically, i don't know if its the pod or what , as i just started using this and not ready to fill another pod yet.It only comes with 2. But when i cover the holes , its a great vape hit everytime , it seems.
