I have been using ElementVape to purchase all my vape juice and kit for 4 years. 1. Good customer service. Has auto confirmation if outside business hour. And they reply within 24 business hour. This is only for their 1st thread, it's not like some corporate each email reply takes another 24 hours 2. On time delivery. It haven't missed any of my package. You also also spend $2-3 for insurance. I had some missing vape juice in a package before, but they immediate send another package after I told them. 3. Juice quality. It depends on what you buy. It has many choices online
