just got my fog... it is a really classy looking mod. i am having trouble with feeding, i tried different combos of pg/vg and it will work for a minute and then horrible dry atty taste. i will unscrew the top to feed more juice into the atty but didn't think i would have to do that every few hits with an auto system, also tried primary inhales and covering the holes. the five ten connect is the same. on the uk forums/reviews it was suggested to use em 901 atties which i bought to use for the fog still getting burnt taste. the only thing i can think of is that the extender doesn't seem to pass the top of the tank like i have seen in videos, the seal is good though, no leakage what so ever and when it works phenomenal flavor and vapor.
in response to the question whether the riva works with the fog, it indeed does, i bought the steel LE -true 3.7- strictly for the fog so i can run lr atties at a good voltage.
for those having atty connection problems, the pin that connects the battery to the atty unscrews and adjusts working similar to adjusting the pin on a gg. i have done this without leakage and discovered this in an effort to diagnose the feeding problem.
any one have any suggestions on the feeding issue? much appreciated
