3-4 drops might work for an 801 but will flood a 510. 2 drops is more than enough to give 6-10 hits, which 10 equates to a stinky.
If you are leaking all over the place, and using carts, your cart material is no suspending the liquid properly and requires fine tuning.
I am still getting the hang of knowing when the vape is out of liquid vs flooded etc. so I know I'm mostly to blame, I am wayyy overfilling because I think I keep reading different "carts" and I am putting more drops in. It is the standard cart and standard fill (for now, I have the blue stuff on order). I played with it, but I guess I don't really know how to check, or fix the stuffing.
So far dripping has been more of a mess, but I haven't been accurate enough to drop only 2, I need to try using a lot less.
Does the filling ever get sucked dry? It seems like it dries on top but it doesn't really pick up the moisture from the bottom so well, causing the user to have to top off the cart. I really like using a cart > dripping, just less work I would think, but I am starting to think that the cart is just annoying if it doesn't hold the liquid like it's supposed to!
So was the first reply correct though that even if it is no overfilled it still has a tendency to leak? Because I know after it seemed like I unflooded the atty, it still seems like I'll get some moisture out there when I look sometimes. This just annoys me because I'll probably have to find a way to hold the PV where it won't be able to leak oil into my pocket/pocket contents.
