I might not get 100 puffs from it, but I'd estimate 60-70 easily.
Hell, I chain-puff on one cart on my way into work (30 minute drive, taking 1-3 puffs every minute), and generally that same cart will make it through 1-2 more breaks afterwards.
I refill in the evenings when I'm using my at-home device, a 601 pipe, and syringe fill the cart so it's positively full, then I like to put 3-4 more drops on the wick afterwards and use the atty as a cap. It sits overnight and seems to keep from getting additional juice in my mouth the next morning, while providing good hits until almost halway through that next day. This is my normal vape- dekang menthol 16mg.
