I'll start with the front light: The brightness is very convincing, even on unlit paths to get with this light ahead relatively quickly, for this price range, which is great. However, the light cone is of a flashlight, so circular, (bothers me not that, but it should be noted), the adjustment of the focal length works perfectly. The mount does what it should, I would certainly not be described as Outrageous. A solid stall screw I lost (that was definitely my fault because I have not turned firmly enough to remove the lamp) for a more stable, better support, this would but probably not so easy to do. For taillight: With the brightness I am also very satisfied, the adjustment of the modes will first require a little Fingerspitzengefuehl, but is later (almost) without any problems. Like some others I did however notice must that the taillight already starts at slight vibrations. Through a paper wedge inside which is quite easy to fix, it is not pleasing anyway. In addition, my turning up the battery compartment of the rubber sealing ring is in the second (!) Come in contrary parts and seems at all quite porous. I find that quite disappointing, hopefully the light is still reasonably waterproof, previously it seemed to be. With regard to burning time and utilization of batteries I can not say much, did the lighting uses up now ca 5h, to the extent any problems. Due to the almost banal and probably easily be solved by the manufacturer defects that have disappointed me, despite good quality of light only 3/5
