ZFM is the 'Cat's Meow'

ZFM - Zero Filler Mod by SCOTTYBALLS is the absolute best mod I found for my 510.

Just pop off the cart and squeeze massive amounts of juice, pop it back on and your vaping before your Atty cools down.

Thanks 'SCOTTYBALLS' I was about to give up on eCigs because I was constantly having to fill my cart that had foam in it.

This is 10X faster.

Just don't confuse your e-liquid with your Insulin....

I'm one of the fortunate ones that don't have Diabetes.

Just thought I would share pics of my mod.

It took me about 10 minutes to make.

Glad to see its working for you !
