Just be aware to note any changes you might experience with the the PG or VG. It's not a problem for most people, but it almost made me quit vaping when I started having some weird symptoms after going to PG. I didn't realize I was switching from 100% VG to PG, so I thought it was just the vaping, period. So it might be a good idea to note what you're buying and stick with it awhile before switching around so you can note the differences. PG was a problem for me, but for others VG is. And like I said, most people have no problem at all. Happy vaping!
