Positive are unquestionably the brightness and battery life, high-I am also satisfied. The many little problems from other reviews (detent mechanism of the focus adjustment, battery cover) I can understand some, but these are in my opinion not all non-purchase reasons and would be me may not misbehaving.
But what I find really problematic is the comfort: direct sitting on the hair I have to adjust the rubber so tight that it hurts after a few minutes and becomes evident imprints of lamp holder on the forehead. In addition, the rear part of the battery slips through shocks while running constantly down and then is (the easier to sweaty hair, because the rear part as opposed to the lamp part no foam pad has) on the neck. Then Subtracting the lamp again high, the gums dissolve easily at the suspension of the rear part. I was so close to being to return the lamp, but they have tried again in a lot of hours of night skiing with cap - and lo and behold, it runs quite enjoyable and slip no longer tolerable in print. The downside of course is that through the screen of a cap no direct illumination of the area directly in front of the feet is possible (which personally I do not mind).
More, however, rather unimportant criticisms are:
- If one of the light cone big one, formed exactly in the middle, a darker stain
- While wearing the lamp, one does not know whether the back light will light or not (the on / off operation feels the same and you can see the red glow of the rear lamp without mirrors or similar).
Conclusion: Good light, but for runners because the wearability only conditionally recommendable.
