I can vouch for this product's quality as well as this company's determination to ensure their customers the best service possible. Through my own fault, I had damaged my Z2s, and through a process of communicating and explaining my situation, the customer support team went above and beyond to make sure I was satisfied. They demonstrated a willingness to show me that I was important to them both as a customer and as a person. They repaired and replaced my product in a manner that was so swift that there was hardly any downtime between me not having my Z2s and me receiving my new Z2s in the mail. I am very appreciative for their measures in showing me that I was appreciated as well.
