I have been buying my liquid for the last 7 years, I recently started to mix my own and have to say I'm very pleased with it. I do have a question about though. It seems that I use much more liquid then I have in the past. Is it the liquid or am I really just enjoying it ? My juice is 70vg 30 pg, I use 8% flavoring. If I'm correct the juice I used for so long was 75/25, is there a big difference ?
