If one were to fill up an empty cartridge with juice, and use the Joye 510, can you tell me about how many drags you can get before you have to refill the cartridge? I'm curious.
Thanks.
I use a Joye 510 with an atty/cart system and I love it! I use a cart filler mod, so I get probably around 25-30 drags? I've never counted, so I'm not sure.
I use a mix of Highping's Cart Mod (look this up in a search) and my own little touch to the mod: I use about 2/3 less of filler than what comes in a pre-filled cart. I also use Ultra Densified Poly-fil, which holds a LOT more juice than normal filler. I cut a piece of filler, then roll it up. I then make a point at the end of the rolled filler, and cut about a 1/2" worth off. If done right, it's a 1/2" cone-shaped filler. I then put a few drops in an empty cartridge, then stick the cone-shape poly-fil in the cart, and then add more drops. The point of the cone should go into the cart, so the cone "base" is hugging the open end of the cart. If you use this, and no vapor comes out, the filler is too thick. Cut UPWARD (length-part, not the base part), so the length is still 1/2" but it's not too thick.

Hope this helps. My cone-shape cart mod, with Highping's Cart Mod help, makes my carts last a LONG time (approximately an hour with moderate vaping).
