I have had nothing but frustration with this business... IF you can call it that! The charger was NOT genuine. Did not charge and got SO HOT! Had to send it back, and had to argue to get a refund and not replacement. Then had to wait... still waiting for a refund! I have spoken to them several times and will be contacting Amerian Express today if the refund does not come through! It has been over 3 weeks! 24 Hour Chargers did not do even ONE thing stated on their website! A scam of a business! Wish I knew what else to do to report the awfulness. JUST STAY AWAY
