Input: We had bought another product that did not work with the new Kindle and were surprised at how helpful you were. You answered so many questions about our product it saved us from returning it. So we ordered this charger which works perfectly for what we wanted. No problems now to report on your products, we love them. Thanks all in advance. Carol B. Kleczka Oregon
