Toddwrote a review of NiteRider Sentinel 250 Tail Light on October 28, 2019
Familiarity: I've used it several times
Bought this for some early morning roadie expeditions. This is an awesome light, especially for the price. Battery life is better than expected, especially for how bright the light is. Highly recommend for a nice light to be seen by cars, and works great in the daytime too.
