i had both of my ego batts do something weird about the time the 30 day warranty ran out. neither will charge, even though the charger lights don't indicate a malfunction. i have been buying replacement parts because madvapes doesn't want to replace them because it was a few days after 30 day warranty expired that this happened. i have filed a complaint with them today because even the new batt i got a few days ago will not charge. new usb charge cords didn't help either. anybody else know what i am talking about? is there something i am not doing right? seems like a lot of money to throw out the window. and now i have nic-fits again. i am kind of new to the vaping scene and could use some commiseration and info. thanks!
