The battery for my Ororo vest was not working correctly. I reported this and was given instructions on how to return the battery for assessment and I included additional information about the problem. Shortly after mailing, I received a message that I was to receive a new battery which arrived in a short period of time. The new battery is working fine. I was happy with the prompt, courteous service and the positive resolution to my problem. I love the vest and would definitely recommend this product.
