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 Greg Roberts

The properties of this lamp work by definition. My caveat in giving it a fifth star is due to the strap. I live in a colder climate and walk outside year round. In winter I wear a thick jacket. The straps could have been expanded in my opinion to allow for a more comfortable fit when carrying more clothing. It looks like it's intended for people who wear warmer clothes. I'm tall and not too tall, but when I wear layers, both belts are stretched to the limit. a cut according to seasonal clothing would be a great idea for five starts!
