I started
vaping almost a year ago .. And been reading here a bit longer. What made me switch some premade juices were not always the same taste and some juices just didn't live up to the what I was expecting for flavor. After reading for a long while I decided to give it a try. I was a bit dissapointed at first, that it wasn't working out so well, but didn't give up. I picked it up again ... But all the juice I make now is just wonderfull and like I want it
Pros
----
1: you can make it yourself
2: you can finetune it to your needs/likes
3: you are not dependant on a supplier having stock of your favorite juices
4: you can make whatever juice/flavors you want
5: if someone decides to ban ejuice/ecigarettes, you already know how to handle it
and last : it can be cheaper (see my cons also)
Cons
-----
1: getting a flavor good for you can be quite costly (like if you buy all fruit flavor X from all vendors)
2: it is not as easy at it seems sometimes, due to the time you have to put in (I do not mind)
3: you got to have patience and not to expect everything will be great from day 1
The cons list is not a really cons list, but more like the downside you know upfront. For me DIY and messing around with rebuildables is more and more becoming a hobby. I haven't made a non vapeable juice in ages now. And everything that I make these days turns up at least OK. I just like fiddling with stuff and trying stuff out. I am a programmer and build software, this is just another thing. Nothing more satisfying then mixing and finding the uber mix or the sweet spot for all the flavors
For the cheaper part ... yes and no, since I have been ordering flavors all over the world, and got around 70-80 flavors and experiment alot, I have some goto juices, but I vape alot of different things. But if you for instance like fruit flavor Y from vendor B, and that's the only thing you want to vape, yes, it's only a fraction of the normal cost. If you are more the adventurous type, not so
All this is based on my own opinion, and might not be the case for other people. I know I am futureproof, will never go back to an analog and will keep on vaping and have some fun doing it
