Brightness super - but extremely short lifetime

I bought the Headlight in July for a vacation in the Australian outback. First of all I was impressed by the brightness and the different levels of brightness. It is remarkable, which may generate such a small lamp for a light. However, I can here only awarded one star, because the positive overall picture has tarnished very quickly.

After less than 2 weeks (use daily 1-2 Std.), The first lamp fell off completely. It should be noted that the lamp has been used throughout properly during the time. A spontaneous failure in the middle of the outback is more than annoying. What is, however, moved me to the final negative assessment of the fact that my wife has experienced with her identical Headlight EXACTLY the same mistake - again, after about two weeks total failure.

The price is good, but for such a low reliability still much too high. Unfortunately, once again an example of the category "You get what you pay for ... or even less."
