Man I'm disgusted ... I bought my first box mod and received it no more than a month ago. I also purchased 4 of the TF 14500 along with a TF charger. After less than a month, 2 of the 4 batts wouldn't hold a charge, and I'm not even sure both the charging ports on the TF charger are functioning correctly. One of the charging ports always shows a green light, no matter whether there's a dead batt on it or not! So yesterday I bought the pricier AW 14500 batts. MAN this burns me! Is the TF charger also crap? If so, what should I get?
