Hi,I started using my old aspire GT tank again and bought the .7 coils to use in it,I always used them before as they give out a good flavour and still do.However they only seem to last around 12ml of juice before it's time to replace them.I vape 60vg dessert flavour juice and only puff away on 14w,now are the 1.0 coils any better for longetivity?I've used the .7 mesh coil before but seem to remember they didn't last long either.I want to continue using the tank for the good flavour but can't really justify buying loads of coils,any help much appreciated, thanks.
