I made the mistake of buying my PG and VG bases from the company I purchase my flavors from....not because I didn't like Vapers Tek (which is the brand of VG/PG I started with), but because I was trying to keep from ordering from so many different places. Well that turned out to be a HUGE mistake! I found that the other brand was inferior in look, smell, flavor, mixing ability, etc. Needless to say, I won't make that mistake again! I know a lot of people say it doesn't matter what brand of VG or PG you use, but I disagree! I can definitely tell a difference! I found the other PG to be more watery and when I would shake a freshly mixed bottle of juice it would turn cloudy....never saw that when I was using all Vapers Tek brand for my VG/PG. Mind you, that was the only thing that had changed....not a first time recipe or new flavor brand/flavor. After that experience I vowed I would never buy or try another brand for my PG/VG needs. I personally believe that Vapers Tek PG and VG is worth the extra cost....it's high quality and pure.
