Obviously depends on your build. I'm running a .8 ohm Clapton build at 35 watts and I'd say it's middle of the road on consumption. It doesn't guzzle but its not sipping it either. Similar to a bachelor tank if you have one of those.
Now I am filling it at least twice a day but that's because its such an awesome Vape, I'm hitting it more than any other setups in my rotation!
And when I say rotation...
Merlin front and center, yeah its that good.
Same old problem to get stuff here aaggg..
