Review on 🚲 NiteRider Sentinel 150 Lumens USB Rechargeable Bike Tail Light - Powerful Lasers, Daylight Visibility - Easy Installation for Men, Women - Road, Mountain, City Commuting, Cycling Safety Flash by Zach Peterson

I like the brightness and the different lighting options but it doesn't last as long as advertised. The strap does not fit airbike seat posts because it slides to both sides while riding. I'm constantly trying to center the light on every ride and it's annoying. I've had the light for over a year now and once I replaced the strap because it broke. Now the main light button didn't work until I took it apart and played around with it. Overall I love the light, I just wish there was a better aero seatpost strap.
