Been using mega atty and mega cart for a couple of weeks now and love them. Bigger, better, yet gentler hit than normally atty/cart....at least in my opinion. The capacity is tremendous, running up to about 60 drops in the cart. Personally I have had great success using the stock filler that comes with the mega cart...as long as I observe the following:
(1) Don't go completely full. 60 drops gives me leakage until vaped down a bit. Starting with 40-45 drops seems to work well.
(2) Only 1 primer drop on new cart refill. Two drops seems to flood a bit, while 1 drop just barely floods for the first couple of hits.
(3) Keep eGo on it's side until you have vaped through about 1/2 the cart. Otherwise I seem to get some flooding and leakage. After 1/2 used standing on end seems pretty much OK. In the meantime if you get a dry vape just set the eGo on end for 20 seconds and go from there.
No science to it, but this seems to work for me. I guess different juices, altitudes, barometric pressures, etc, could make a difference as well.
