After the warranty it is dangerous due to the obsolescence!

I give this product 2 stars because it has lit me two years off. No more no less. Now it has stopped illuminating, but still on the bike! Too dangerous. Two stars because the beam is useful and very bright. You will definitely seen and sees others and hidden something

After exactly two years and 3 months is the "thread" front, the light Körber, the open decay of the battery compartment, out gebroche whatsoever. Just like that moment during the journey and just falls off the light Körber and you're in the middle of an unlit country road! Now search times since then by herraus geallenen battery back together!

The next point is obsolende actual holder, with which the lamp on the handlebars is determined genknipst. This bracket locks via a quick release in plastic barbs. This break in my eyes too much too soon out! Follows it no longer holds its position.

I've marked with a red circle my (two) points of criticism on the two accompanying photographs.

With regard to maturity: The batteries supplied by Sigma are the last crap. Two were already defective at 6 Mona Teten. I Sanyo eneloop exreme 2.450mAh which almost as expensive as these were Sigma light used. These are thanks to this lamp after the light Körber now dropped well over. Thank Sigma!

That was my second and last bicycle lights Sigma.
