This is an updated rating that I am posting here.The seller promptly shipped me another item to replace the first one I received that was defective, after charging and testing the item I can say I am completely satisfied with their product and response to my initial problem. They ask for confirmation of the defective first item and after that sent me a replacement.I will do business with this seller with confidence that I will be treated as a valued customer.
