The small Plaktikhebel to the handlebar holder is terminated after a short time, but in such delicate structures I eh not have too high expectations and also the lamp holder remains fully funtionsfähig. Also, the switch could be a little more specific, because every now and then the light will go only after the second or third button on.
Mir makes this lamp but otherwise very good services, am definitely satisfied. Those who place at a fair price value quality lighting and security, should access.
