I bought an ASUS Zenbook and shortly after 30 days the screen developed a defect. Seven months later, the Zenbook has been returned for repair under warranty TWO times and it still has not been fixed. After pressuring ASUS for a refund, they only offered to trade me a "used" Zenbook. Not what I expected after spending good money on a new unit. Microsoft store customer support (NOT) hid behind the 30 day return policy and denided my request for refund. BAD unit ASUS ZenBook Flip UX360CA from microsoftstore.com
