Ive been vaping for about 5 years now. I used to be part of this forum, but have not visited in a while. I found a set up that worked for me and stuck with it. The problem is my set up is mech mods using carto tanks. the issue is cartomizers are getting harder and harder to find. Im looking for some ideas on something to replace the carto tanks with. Easy to use, works with my mods (GP PAPS). Any advice would be greatly appreciated. Thanks.
