small nuclear flash

I am very pleased with the lamp for over a year. It is mini but highly effective and lights very far. The battery is charged quickly via USB, the holder fits very tightly on the handlebar and fixed the lamp well. Even in the brighter of the two stages of the battery lasts a long time. A second holder for a second bike I bought commercially spot for few euros. The mini USB port is covered by a rubber flap which is a little harder to press in, otherwise it dissolves. Even in heavy rain but nothing has happened yet.
