Review on USB Rechargeable LED Reflective Vest For Night Running, Jogging, And Cycling - High Visibility Safety Belt With Adjustable Waist And Reflector Strips By ECEEN by Richard Kuntz

Bought this vest for cycling at night. I haven't used the signaling feature, just the lights to help motorists see me at night. Unfortunately, the vest spontaneously shuts off sometimes. I can't see when the back panel has shut off, which seems to happen regularly. I don't recommend this product for that reason. It doesn't help me if it's not working. I charge it up completely before each ride, so it's not an issue of losing power. And if I manage to press the power button, it will restart. But if I can't see the back panel, it's impossible to know if it's working or not.
