I can say Janty Liquids are great, I ordered a huge amount of them after trying a few flavors from what I initially ordered and from my brothers stock. I've also tried a bunch of other flavors from different suppliers, some where down right terrible, not just in taste but in vapor productions, ect. They also drip great and don't pour and leak out of the carts (Yes I had this happen with something else)
I also DIY with some flavors of liquid. I have a huge sweet tooth and I love to mix and create my own flavors. Kinda keeps me out of the freezer looking for ice cream
And I use all these on my Ego & V3 without any problems so far.
