great light, but no better than cheap battery light

the light is super, have waited a long time and it now buy it. It meets the advertised features is bright, really shines all around (if you no bulky side pockets has) and the anti-theft switch is also convenient. I miss the (much more expensive) front light Cyo.

But: it is not brighter than my old diode rear light with battery operation. Maybe even a little darker. And the battery light has two AA Eneloop batteries kept forever, more than 10 hours in any case, so it was not a power-hungry. And it was very very cheap times, maybe 10 in a set with a battery front light (which has been good for nothing).
And this feature with the distance measurement for cars may indeed be good, but not new. My cheap battery light had in fact about a dozen LEDs, arranged in a semicircle, the result was the same.

Well, now I have to
1. no longer think to invite batteries (and especially not the charged batteries also reinstate)
2. the light is always on when I'm driving, so during the day. That's a significant gain in safety. I do not regret the purchase.

By the way: without bundled cable. When the headlight of BOOM that was the case, so I have not bought in advance, and then had to specially still looking for a bike shop.
