Review on 🚴 NiteRider Sentry Aero 260: Powerful USB Rechargeable Taillight for Standard & Aero Seatposts by James Jones

(Originally I rated this product much lower as the on/off button didn't work. However, NiteRider replaced it quickly with no problems and now I love the light! Excellent customer service) Two things stand out on light: 1. It is ideal for aero seat tubes (ie with an aero profile). I use it on Cervelo and it fits very securely and never shifts to one side or the other.2. This light is not only very bright directly behind the cyclist, but also incredibly visible from all directions. In heavy traffic, that gives me an extra sense of security. Overall I really like this light and would use it on standard (i.e. round) seatposts as well.
