To me personally it is really an art form and making it by hand meets my needs more than a machine. However, the aspect of human error doesn’t escape me either as an E-Juice maker can easily confuse VG and PG if they are not paying attention and botch up my E-Juice (it’s happened before, most likely will happen again); either way I am happy to see both vendors taking safety and contamination into heavy consideration prior to making and selling their E-Juices. I’ve seen many stores that make their E-Juice out in the open, next to food or drinks, and keeps mixing materials in the bathroom (yuck). Avoid those stores at all costs as the last thing you want in your E-Juice is someone’s lunch!!
