i got a vaporessence liquinator and for a while it was ok. ive had it for abotu two weeks and lately i notice that sometimes vapor production is great. other times i get more vapor from my kr808 batteries(im using the tank on a glv2 5volt) and then the other night i had my mod with the liquinator attatched to it laying on my bedside table and woke up and it was all leaky.everything i heard about this tank has made it seem as though this thing never leakes or has any issues. but it has been trouble since i got it..any ideas??
