### ⭐⭐⭐⭐⭐ Good Visibility, Good Battery Live, Nice Design
*by B***E on July 13, 2025*

This is a very nice rear cycling blinker with excellent battery life. I originally bought this item two years ago. Just replaced it after a battery failure by buying the same unit. I ride pretty much every day, weather permitting, so the two years of reliable performance was, in my opinion, very good. It is easy to mount, easy to take on and off to charge, and is very visible.
