In the city did not rather the problem is that it is at night too dark to see anything, but rather the problem to be overlooked as cyclists ...
Back I have a slightly more expensive, stronger light (with StVZO approval) and mounted on the handlebars I got me now this:
I am completely satisfied, because no matter where I am traveling by bike, whether the university, gymnasium, shopping, etc., my backpack I have almost always present and the LED light is - unless on the handlebars - in the side pocket ...
In the dark, the light is strapped in 10 seconds with the included rubber band on the handlebar and is used in flashing mode as a position light; The police is now even often come to meet me, stopped, or at least asked about it, I was (so far) not yet.
Thanks to the LED technology you have to make any big head because of the battery, so you do not need before each use only NEN technology check if everything works to make ...
The value is in my opinion the top, so I have no negative criticism, only again:
You buy that to be seen, not to illuminate your path!
