I had got coils for this old tank, I thought they specifically had to be M4 coils. I put juice in it, and I taste nothing at all. I noticed my newer vape has mesh coils, and lots of flavor... So yeah, this tank is just sitting around and I'd love to use it, can I get the newer V12 mesh coils and put em in? They look identical, I just wanna double check before buying them.
