Welcome to both of you new people , but $20.00 for a device , is not going to get you very much . 50 to 60.00 area , will bring a lot more choices for devices that will give you a better vaping experience . It's good that the Ego got you started , but a 350 mah battery won't last very long between charges . If you only have the one , your out of luck , until it gets charged up . Eventually , you need to have back-ups for everything . Devices , carto's or atty's , tanks , or whatever , extra batteries , chargers , juice , etc . I was asked the other day at the car dealership , where I was getting my truck , serviced , how many devices did I have . My resonse was , on me , or with me , and in my truck ?? In that case 11 . 8 Ego's with tanks , atty's and carto's . a Provari , a Reo "Grand" , and a Zmax . Yes that's a bit extreme , but hey , I never get caught without .
