The JOYE 510 is the best e cigarette ever made, with a manual button to control the atomizer activation. Slim and stylish, this manual e cigarette beats the Screwdriver and GG models, in functionality and fit. I haven’t used any other model of e cigarette since I tried the JOYE 510. Our kit includes 2 Black batteries w/ Blue LED, 2 Black atomizers, a wall charger and 5 cartridges. Everything you need to get started, except for smoke juice. And best of all it comes with a 1 year warranty. If anything goes wrong with your Joy 510 we will replace the defective part for 1 year.
