the sign in front just says«Metro PCS.» Emu might have been the old name. poor quality products, but what do you expect from a $ 10 generic car charger? i also bought a $ 10 generic regular charger. these are both for my samsung cell. my samsung charger was lost, so i bought a replacement here. the charger beeps continuously once it thinks my battery is full. however, the battery is not full and it does this which is extremely annoying in the middle of then night. i know it is not my phone, because it does not do this with a legitimate samsung charger. as for the car charger, it stopped working after a few months. i tried to exchange it at this store and they said all sales are final. needless to say, i will spend the extra money to buy those 2 chargers from samsung directly and i will never go back into this store as they cannot take care of my problems. if this were the sprint store, they would have just replaced my charger if it wasn’t working. don’t go here!
