This a good light to be seen, but not to see in dark conditions. It has a 180-degree view, but the light isn't focused so you can't use it for night riding. That's fine as I bought this to be seen. The only criticism I have is the battery. As it's winter, I haven't used this on a long ride, but it seems like 5-6 hours is the max battery life on even lower setting. It also takes a long time to charge. So don't use it at night and don't expect it to last on a long ride and it's fine.
Great light. Wish it came with an attachment that made it flush against head tube
