I ordered the lamp, because I was looking for a Kompflampe for my running training in the dark winter months. More favorable lamps did not have such a good illumination and narrow rubber holders, so we had to drag solid, which also may ever lead to headaches. In this light, I have no such problems. It lights up very well, so you can wonderfully amount also dark forest roads or rural roads with potholes and big puddles. The comfort is very pleasant. The power button can be disabled by pressing and holding, so that the lamp is not accidentally turned on in the sports bag if something comes to the pressure switch. The housing acts not very high, but not cheap at first glance. I can only say, if it is even fell down what it endures. Waterproof against heavy rain or snow, the lamp anyway. I am for peace so far and very would buy again.
