I know that juice in the PV is an issue when dripping, but since I started using the liquinator I have had no juice leak down into the buzz at all! Whenever I change the batteries I use a wad of paper towels to clean out the battery end of the PV. I got into this habbit because other attys and tanks tended to leak a bit into my battery or my borrowed buzz (sorry wharf, but I did clean it every night) I am new to cartomizers, liquinators and Buzz's, but since I have had this combination, not a drop. Have I just been lucky or is this a problem I can expect eventually!
