The lights have really liked me at first, because they are really small, they fit in your pocket if you times can be his bike somewhere. The light output is impressive, but just to be seen or to go on an illuminated city. Unfortunately, the silicone is not too durable and is porous and brittle after repeated use. However, when you consider that what cost these lights and still (in my case) one year are ready then I can recommend you with a clear conscience on.
