I recently purchased a Joye 510 starter kit. Currently i'm using the carts that came with the Joye 510 kit. I find it alittle annoying having to refill the carts alot of times. Also i get alittle messy every now and then having ejuice on my hands and e cig while refiling my carts. I was wondering is it alot more convinence to use a carto instead? Can you vape longer w/ carto comparing to carts? Would it cost me alot more using carto then carts? Roughly about how many packs (5 cartos) would i need per month? I heard they can be refill and can use then for about (more or less) 2 - 3 refills. Also what is the difference between using a carto and cart? Will i get a better throat hit, better vaping experience, etc?
Thank you all
