I like the product, it really worked but after 10/11 months it just stopped working, my phones wouldn't charge. And when I contacted the seller he told me the warranty was expired but he would send me a new set. I was very grateful that they listened and replaced and sent a new set without hesitation. This is a great company that listens to their customers' concerns. I am happy with their customer service and will continue to shop if the need arises. Many Thanks.
