Review on 🏃 Zenoplige USB Rechargeable LED Chest Light - Night Running Safety Gear for Outdoor Running, Walking, Camping, Jogging, Hiking - Waterproof Safety Warning Lamp for Runners by Brad Atl

It didn't even last an hour on a full charge. I bought it for an evening half marathon in Joshua Tree, California. About 30 minutes into the race I noticed the lights were getting very dim. I could hardly see. For the next 10 minutes he was completely dead and I would have been pitch black if it weren't for the other runners and their head/body lights. Do yourself a favor and look elsewhere. I am returning this item.
