I'm still fairly new to the world of vaping, I started out with a starter kit from 7-11 Xhale 02. It was good while it lasted. It broke very often but the service was amazing. The owner sent me pieces multiple times knowing I didn't have to get them I could have had to buy them. He sent them to me personally. I even received a phone call from David the LLC of Xhale 02 asking how of was holding up. And if I needed anything. Their service was great! So I finally moved on I was tired of the product breaking. I went and did my research on e cigarettes and decided to go with vapor nine. I have never spoke with Ben personally but I know his team is probably tired of hearing from me. Though all my questions were answered in a timely manor, they also did a check up with me about my order. It took a little longer then normal but that as my fault. I've been hearing a lot about the empty cartridges from v9 and wondering why they would be better then the pre filled ones. I broke down and bought the defender and have nothing but nice things to say about it. The battery will last more then 2 days of continuous use, I also got liquid and extra carts with is. So I haven't smoked a fig in a long time. I just today bought some empty ones and just wantes to see what people have to say about them. Let me know.! Thanks!!
