I just got the new Aspire breeze NXT when my Nautilus AIO stopped working. Both are really great vapes. I never really understood what the difference of these really does, I mainly vape Non-flavored and vape all day basically, otherwise the Nicorette lozenges punch a hole in my wallet every week. Is 50/50 better than 70/30 for this type of vape for maximising life of each coil, or the other way around? I'm trying to reduce my nicotine cost as low as possible.
