The lamps are super. (At the price, of course, no insane build quality) but they do what they should and the good. nice is that you can activate blinking cycles as desired. Now to mount: The mounting of the headlamp is attached in order and quickly. However, the mounting for the rear lamp is an absolute bad design. It is advertised to attach to the saddle. However, the orientation is initially wrong times. But that would be acceptable to whether vertical or horizontal is not really matter the main thing it holds and the lamp lights. But the ring collar for attaching to the saddle bar is clearly too small I can hardly imagine that it holds in any saddle. in any case not to my. you can now halt even something cobble together what but yes certainly should not be the point of it.
