I've been e-smoking for about 4 months now and I've noticed that there is alot of liquid at the bottom of my cart still when its time to refill...should I cut the fiber in half and put something non absorbent beneath it to save on liquid? BTW I have a 4072 from Steve (puresmoker) and a sample pack from Christian (johnson creek) if I may add...Ive been using both for 4 months with absolutely no problems!
