worked fine while they lasted which was not long [SEP] these cords worked quite well at first but i thought buying a pack of phone charging cords a few months ago would insure that i would be covered for a good long time at home in my car and on the go wrong at this point only one of the four cords still works so that is not good quality in my opinion especially considering i spread my phone charging needs out over cords total depending on where i am so yeah i would not buy these again i guess you get what you pay for
