So I tried my drip tip on my ego T XL atty and I don't really get it. I am afraid I am going to pop the coil if I don't get enough in there and/or if I hold it too long. I put in 3 or so drop but didn't seem to get much so I add more but I was afraid I would pop it. It seems like I had to draw very slow compared to the tank. Adivse?
