So far so good! Only use it a couple times but it's very easy to install and the light is well distributed and bright
I am very happy with my OLED 1200 Boost Nike light. It lasts for my morning ride and really lights up the road even at medium strength.
I love, love, love the Sentinel 250 tail light so much that this purchase is actually my second. It shines extremely brightly, the flash mode can be seen from an incredibly far distance, and the laser lane lights add additional safety on very dark roads. It is very well designed and built and gives me added peace of mind when riding at nighttime and daytime.
