I have been vaping for almost a year now and I feel pretty solid about what makes my attys die fast: VG

At first I was going through atomizers pretty fast, one every couple of weeks (or more). Then I stopped using all liquids that had VG in them and my atomizers started averaging 2-3 months of good lifespan.

Last month I decided it might just have been luck of the draw or maybe atomizers "got better" and I started using a little VG in my mixes (about 15%). Boom - I went through three atomizers in under a month.

No more VG for me.
