Front lamp:
Advantageously, the three brightness levels. In town the smallest loose enough, what tremendously saves electricity. The illumination is a total fine. However, the cone of light (scattering) could be somewhat broader and more evenly. This is also noticeable at the highest level in dark corners. Floodlight does not have the lamp. Who wants to have it as bright as day at night before the wheel, should resort to another product. The attachment of the holder is somewhat tricky because of the gums. The advantage of the tool-free mounting bring unfortunately the disadvantage of rapid tool-free disassembly (petty theft) with itself. I have therefore the screw is replaced by another. The protective cap of the USB socket sits quite loose. How long that holds remains to be seen.
Rear light:
The taillight is awesome. It lights backwards and to the sides. It is very noticeable and increases my feeling of security immensely. Nevertheless, it is very compact. Again, the cover of the USB socket is pretty loose. The holder is attached quickly with the rubber band. It looks stable. However, I'm worried that it is porous in a few years. A clamp would have liked better than fixing. Also as far as protection against thieves. I have the tape therefore additionally secured with a cable tie.
Charger:
The charger works pretty cheap. The USB cord is very loose. This is for me, however, is not a problem, since I now can swim in USB chargers anyway. Was not the original sense of the USB standard that you do not have to put any device charger that? I know if a charger would be doing would be here now, some experts complain. Bottom line, it does not flow into my rating.
Conclusion:
The lamps are designed for the price ok. The illumination of the front lamp could be a bit better. Because of the loose USB covers and the fiddly holders and the necessary modifications to protect these against opportunist thieves I subtract a star.
