We are very happy with all aspects of our purchase. The order process was fast and easy, this supplier gave great service with easy, friendly and courteous communication. The battery equalization devices we ordered arrived within a few days, were of high quality and worked exactly as described. We highly recommend Changsha Deligreen Power
