Purchased 3 years ago. I only rode my bicycle about once a month, so the usage time was short. There are some scratches and wear due to aging. Please refer to the photos. The light and operation are working fine. I will also include the 4 AA batteries that were in it. Please purchase only if you understand that this is a used item.
