Review on USB Rechargeable Bike Tail Light: 26 Hours of Super Bright LED Illumination, 3 Light Modes for Mountain Bikes, Road Bicycles, Backpacks - Waterproof & Easy Installation by James Salem

I had a similar flashlight for many years. The resemblance ends when you receive the light. The mount is not tilted so it faces the ground when attached to a seatpost or seat tube. The strap is not long enough to secure the seat tube and barely fits on the seat post. I am concerned that the attachment strap hook will not hold. Luckily, the light is very bright for its size, so cars can still see it when it's pointing down. Worst of all, the USB port on the device is terrible. Extreme care is required when connecting and disconnecting the charging connector without damaging the connector. I'm not sure if it will last. Battery life needs to be determined. I give it a generous 4 stars for the battery life. Brightness "3 Settings". Brighter, a little less bright and slow flash. No flash or noticeable pattern. I only use it as daytime running lights. Light, but normal. Until the plug and hook break.
