Excellent quality and for now its illumination is great. I need to use it on the hill at night to see how well it lights up the paths.
A good bike light,shines like a headlight,illuminates the entire width of the road. For long,night rides,the brightness at the first mode of 200 lumens is quite sufficient on asphalt to save battery life. I am very pleased with the remote control operation (three brightness modes,high/low beam,daytime and night flashing). Can be controlled through the app on your phone. I'm considering buying a rear light from the same brand to control two lights at once with one remote. The product is good,high quality,I recommend it! The price is pretty good,too! it needs to be purchased separately!!! I was lucky,I printed the mount on a 3D printer.
