I HAD to learn to DIY as I'm one of those unlucky few who can't vape PG...
Very few vendors actually know how to make great, or even so-so, 100% VG. I was spending so much money trying to find something that I could actually vape that did NOT taste like I'd be better off trying to vape Olive Oil (which I do like and is the ONLY oil that I cook with) that I almost FELL, and started smoking again.

When I think of all of the GG's I could have bought with all of that, it really makes me even sicker...
Just when it all seemed like an impossibility, I found 1 new vendor and it saved me!!! Their 100% VG was GREAT!!! For a few months that is... Then they closed shop and ripped me off on my last $80.00order!

My Discover Card got my money back for me (the ONLY good thing about Credit Cards).
The next vendor that I tried on my first order actually caused my brand new, Joye attys to come apart in pieces!!! At first I thought it was just that flavor, but no after five more flavors and five more attys, WRONG!!!

I now know the entire internal workings of an atty not that I really wanted to, at that time anyway... I had spent well over $100.00 on that e-juice, not counting my attys and my PINK ones at that, too! That vendor replaced my Joyes with some nasty tasting attys and sent me more e-juice mixed with a bunch of Everclear that his "Professional Mixologist" came up with. Good thing it made me sick,

as one of my Mod Making/Vending friends told me that it was dangerous also in that it could have caused an explosion!!!
Bound and determined to keep my promise to my Father, who had recently passed away, that I would quit smoking I decided to give DIY a try... I mean after all I had tried, it wouldn't be any real effort on my part to do any worse,

and NEVER wanted to have to rely upon anyone else nor end up in any of those situations again!!! My first attempt was GREAT and I've been a Happy Vaper every since...

So what my nightmare/story all boils down to is that very old, but true saying, "Necessity is the Mother of Invention".
BTW mine works great with the AVS and AFSV2!!! I use 100% VG, with a LOT of flavoring...
