Hello,
I brought a similar one from ebay myself, quality VERY low. Also is not cycling specific is also marketed as a strap on headlamp/torch; quick release mount is an after thought and has way too much play (had to put tape on to fill the gaps). The switch regularly fails so the light does not work. But worst of all after little use 1\3 of the led’s have failed. Do your self a favour and buy some junk led light from the local supermarket, then you can return it if it goes lame. Otherwise fork out a bit extra and get something that someone will put their brand name on. Cycle specific light will at least have a better mount.
