Light, bright and light again ... but also cheap

I was surprised how bright the lamp when I'm driving. Should the lamp be inappropriate as far down I would have certainly scared dazzling other. The status light on the other hand does not light up really strong, but still. The cone of light is getting used to. Apparently the light is reflected from its own built-in reflector and throws additionally comical pattern on the edge. But I think that's matter of habit.

Why the bad review? What is ugly is the processing. I do not expect big but the problems started already at the time of installation. I have the same lamp mounted instead of the supplied bracket (as in the picture) on the bicycle. While I constantly crumbled pulled the bolts from silver booze and it creaked slightly. The screw was a little smaller than the hole, and I have something further bent the disturbing elements apart when I noticed that the lamp can withstand so much. In the end I had a crack in it, and the lamp sat really firmly without. I find it remarkable how cheap the material on the holder is. Even little worse and you could save quite the same lamp.

I can not say anything to the sensor since I simply let the lamp "on" and my pros and rear light only on the Dynamo tax (rotates or not).

At the end: The price is for ~ 20 still okay. More I would not give it. I'd rather take the sensor and the continuation of the cable to the rear light have a solid light that promises longer hold, but unfortunately I have yet discovered no alternative.
