Review on ⚡️ Delta Cycle & Home Safety Light 2-Pack: Ultra-Bright USB Rechargeable Outdoor Lights for Night Walking, Running, Jogging, and Biking by Wendell Chapman

Bought a set of two from Revain. A block was dead out of the box. I charged it for over an hour and it came to a half dead state. When indicating charging, the LED was very dim compared to the other device, and when powering up, the flash of light was noticeably dimmer (50%) than the other device. Have contacted the manufacturer. There was a delay in replying, they said they missed my message. I was hoping they would only replace one block but they didn't. Told me to send them back to Revain so they went back for a refund. Due to the issues I've had I will switch to a different product and hope for better results.
