The lamp itself was fine, small and light. Unfortunately, it has fallen already at the 2nd drive out of the bracket, which I have noted down immediately, and thus the lamp is now off. Pretty bad value for money: one-way lamp, life that was the way with the bike on a country road. A fortiori not be used for MTB. Possibly for quite quiet rides Hollandrad on fresh asphalt surfaces. Definitely not buy recommendation!
