i got a few kinds i know for sure i got boge, a few joye ones, some ones i dont know who makes them but they are black/stainless with solid tips(not soft tips) and some have sliver others have brass ends but idk the makers of these i got them off a site on clearance and i cant find the email from buying so idk the sites name. the only ones i havnt tryed are the ce-2 ones but if a find a site that has them instock ima try them because they look like they are better and might do better with vg base liquids just guessing because of the build of them. id stick with attys but i seem to be a atty killer. i cant get an atty to last more then a day or two beacuse im heavy vaperer and even if i clean them i cantseem to keep attys alive so i just stick with carts. but i will try and use more 50/50 liquids once i get some. for now im just mixing my old 100 and 80/20 pgs with my 100vgs to help thin them down untill i find a good mix that works
i do know the i can get my boge carts to last a while if i clean them every few days using the coke way and running under hot water. atm i mix a 80pg20vg with a 100vg liquid and it seems to work but if i dont make the mix right it gunks up the carts after a fill or 2
