Still getting leaking from your blue foam try this

[Memnoch D]

I tried trimming the cartridge a little bit today just to see what it would do. Was amazed by what a simple thing like that did. I cut it about a cm away from the holes on the side of the cartridge, stuck my blue foam back in, and was getting a lot of vapor and absolutely no leakage. I then filled my cartridge up to the very top, stuck the foam back in, fluid was leaking out the sides of course from it being so full. I tried it again, still no leakage no matter how hard I pulled on it. I recommend giving it a try if you are tired of getting juice in your mouth.

Are you saying you trimmed the actual cartridge, or you trimmed the blue foam further? I don't understand how trimming the cartridge would solve the leaking problem? Maybe I'm slow. I use the blue foam mod as normal and I rarely get any leaking. Only when I overfill the cart.

a cm? Do you mean a mm? And what kind of carts? I cannot picture this.
