I have used atomizer + cartridge myself and I promised to set up my brother for vaping. So, he got Joye batteries and Boge cartomizers. The problem is, there's no decent vape, no taste at all, just barely smoke. Tried 2 different batteries he bought and 2 cartomizers, no results. Same liquid on my DSE atomizer + cartridge gives great flavour and plenty of smoke so it's not the liquid. Someone told me it's because cartomizers are 2.7 ohm and not 2.0 ohm. But could the difference be this big ? Now the results I am getting for him are pretty much the same I got when I was starting out and I had a DOA atty.
