The decision much to this model, since I'm mainly on the town and here the bike paths and streets are mostly eh illuminated. A decisive factor was dying for me the size and the weight of the lamp. They can easily be stowed in each jacket while shopping or going to the movies and do not mind in the pocket. Luminosity is the size really good. My old model was twice as big and not as bright. I use the LED lamp with 2600mAh battery and am satisfied with the operation time. However, I do not reach the 20 per hours burn time. At least not if you do not want to miss out on the full brightness of the lamp. But for the light output and the two AA batteries that is my opinion, after all right.
To hold you have to say not much. Sits good, is not too broad (ie also for handlebars without much "straight" course suitable) and can be at request completely, without tools, to lose weight.
Definitely a buy recommendation on my part.
