The bicycle light is top. The ads for the light intensity and the remaining burn time are also very useful - after all, has its price. The holder is however getting used to for me the possibility of movement to the right and left turn is very convenient. The method of attachment bothers me. Initially, the holder loosened again. Now I hope to bow out reasonably to have and hope that the holder will keep on tapered handlebar. Instead of the USB charging cable, a charging power supply would have pleased me more included in any case.
