Mine is from China and 3 years old now without any problems. I make sure to fully drain the battery and unplug it when I notice its fully charged. My only complaint is that the beams are not focused very well so I have to tilt it down on the MUP and roads so not to blind oncoming vehicles and pedestrians.
