I'm an out of towner who was fouling things up with my new device. The girl at the store was so awesome. She taught me what I was doing wrong and how to fix it. We worked on making a juice that was like the first juice I ever vaped. I can't say it was like the first juice because it is SOOOOOO much better. It's perfect. Seriously, this store knows its business. Knowledgeable, intuitive, and eager to make its customers happy. I am so pleased with their service and knowledge. Next time I'm passing through, I'm stopping in!!!!!!
