Ordered my first e cig. I decided to go with a Joye 510-t system. Reading reviews some people say it burns through e-liquid quickly, also some people say the batteries run out quickly, other say they do not. Can anyone tell me what problems I need to watch out for (like leaks), warning signs of malfunction, or anything like that? Also ordered 15ml of %100 percent VG juice from Velvet Cloud Vapor in Ice beard Menthol flavor, that stuff sounds so tasty I can't wait to try it. Any feedback appreciated.
