Got the headlamp brought primarily for jogging, but they put a well at the evening cycling and for DIY. Granted I did not expect too much for the price and was rather skeptical that the lamp can really suck what. Upon delivery I was pleasantly surprised. The lamp is not the best impression is, however, processed acceptable for the price. The elastic bands provide a good grip on the head and the actual lamp can be adjusted in angle, which is really helpful. In addition, you can choose three different levels of brightness. These differ in the number of LEDs that are switched (01.08.21) where you will even almost blinded in the highest level of the light. In addition, there is a flashing mode with all 21 LEDs. The lamp changing from a relatively large angle, so that one has not only illuminated a small sports, special cone of light is pleasantly wide. It is operated via 3 AAA batteries and the battery compartment is provided with a rubber seal. A first run in the rain has survived the lamp easily. As described, the lamp is also suitable for sports. However, while jogging it bobs due to the design with a little, but this has not bothered me. When biking is worth gold and a great addition to the actual lighting on the bike just in the dark winter months. For the price you really can not go wrong. I've been buying despite initial skepticism, no regrets. However, please do not expect any 100 euros Quality.
