Just got a set at a local b&m here in San Antonio and vaped off one for maybe an hour and a half ...went through maybe 3mls of juice or how ever mush is used when you drip about 5 drops every ten minutes. Is my battery already dead? Im so confused cuz it won't fire and the other one works just fine. Is this normally how long they last? Or do they come halfway charged? I was recommended a "flavor build" which was 26g 5or6 wraps on a 2mm bit pushing about .3 ohm's ...Please help me understand??
