Review on Rechargeable LED Chest Light Back Warning Light by ALOVECO - Ideal for Night Running, Camping, Hiking, Jogging, and Outdoor Adventures - 4 Lighting Modes with 90° Adjustable Beam by Johnny Snyder

This was a life saver when the days were getting shorter and when you got home from work the only option was to walk in the dark. They are quite bright and the battery lasts quite long (about 5 hours). It takes a little getting used to wearing it, but after a few runs it feels good. The only downside was that the light soon stopped staying in place. it will turn no matter how much I adjust it. It still protected me, hence the 4 stars.
