Thanks for the replies and help. How about where is the best place to buy 510 attys and carts. Thanks again. Happy vaping
I buy mine from Totally Wicked when they have a sale, too expensive otherwise. Health Cabin sells them for a good price, as does East-Mall, although with those two vendors you are ordering from China and there is more shipping charges and sometimes a longer wait. I prefer to order inside the US. Carts are generally on sale when attys are.
As for drops, about 10 - 14 depending on the cart filler. Many, if not most of 510 users here don't use the stock filler material anymore, as it holds on to juice too much, gets compressed too much from the atty bridge, and is too inconsistent in its performance. Blue foam instead of stock filler is very popular (aquarium filter foam). Some use the Pyramid Tea Bag material as filler, with good results. I use one of the cart mods, zero-filler mod, which basically allows the cart to be a dripping reservior, without filler, and I use a syringe to inject juice into the cart...so its 0.5 mL for me, not usually drops.
Drop size also depends on the thickness of the juice, so rather than counting drops, its generally whatever it takes to fill the cart so the juice is pooling on top.
