I don't know if it''s just the way i'm using them, but do the boge carto's lose their sizzle after a few days of use? My first couple days they would crackle, pop and produce tons of flavor and vapor. But on my 3rd day of use they don't seem to be producing much flavor or vapor. I am making sure I keep the filler nice and damp. I am getting that "slushy" look at the top. But hear none of the crackling sound anymore or getting that great TH and vapor production. Any tips or tricks anyone might have would be greatly appreciated!!
