I have had the gogo for just over 24hr and I couldn't wait for the first cart to go dry and fill it with my fav for now ry4..as soon as I smelt the 1st bit of burn I stopped and topped of the cart to the point where it dripped from the bottom dried everything of spun the carto in my hand for good luck and the first 3 puffs felt like I was smoking straight filler..now that it has set for a while it tastes like half burn\half ry4
