works great , i use it in my AC9 but you do have to change it out after a couple of days or so , i have been making a hybrid wick that i like better , just picture what a Qtip looks like and i use ss mesh with a thin to med wrap of cotton on top , cotton wicks slow the mesh helps to wick faster and i can get 3-4 days b4 changing it out , you can also do it on a protank too its a little different i do ss mesh with cotton inside the mesh works great
