Depends on how sensitive your taste is. What did you think of the difference between MFS and
ecigexpress? I have only ordered nic from 2 vendors. 1st ever was voidmist . Since it was my first , I had no othe comps. All others have been from Wizard Labs. They have
three varieties.
Regular organic,Wizards Ice and Ultra Pure. I believe you have to request the 2nd two. I will say that I thought the Ultra Pure was great.Very clear like water and tasted very clean. I have also read about XtremeVaping having very high quality nic and ECX also being of very high quality.
Sorry about my limited input,thats all I have.
