Sun, I'm actually topping off the carts that came with it. Only had this cart 2 days I thought maybe...ok, stay with me here..lol. I thought the cart wool might be like a new bath towel, how they aren't terribly absorbent until you wash 'em a couple times? So I pulled out the cart wool, rinsed and dried thoroughly and refilled using Igetcha's method from the video. Still same thing. I'm not pooling the liquid on top, and leaving it in a vertical position for a few mins seems to give me a few more hits when the cart seems exhausted. Also can taste a change in the flavor when its running low. But when I pop off the cart to top it, sure enough, the wool is still pretty wet.
I don't seem to have to top off more than any of the other 901 users have posted. About 3 cigs worth of
vaping and then 3-4 drops to top off. Just kinda curious how much liquid is left in the cart when it's "spent".
