Again, you can safely connect the many positive reviews. That's light !!! I am absolutely amazed at what comes out of this lamp. The lamp is certainly not cheap, but first, it's still more expensive (maybe lighter) and secondly has quality now times their price. The main features have already been sufficiently described and meet also. The lamp is easily mounted on a bracket with screw quickly and without tools to the handlebars. On the holder, the lamp is then slid and locked. Pragmatic and sufficient. It is operated with four enclosed battery's of BM, which I could not make fullest and therefore can not say anything at runtime. With the battery's lamp is one certainly not to the lightweights, sitting with me but surely and firmly in the bracket. They could also drive vibrations as sidewalks down so far not impressed. There clearly 5 Star with recommendation.
