Everything was super until yesterday, then I turned on the light on the way home and after that it could no longer be off when pressing the lamp and the battery lights went out, but when you release both went again. Then I have the batteries taken out short and plugged back, and then it was the other way around the lamp went on only when you hold down the button, but the battery lamp always remained off.
So I emailed directly Sigma evening, with no expectation that it brings something, as I unfortunately did not have the receipt and purely legal point would have no chance. The next morning I had an answer, in which it was offered, the lamp to check for free and replaced if necessary.
However, I had an idea and have expanded the battery and allow the lamp to be overnight, then installed the batteries. Now it's back. But nevertheless, kudos to Sigma for their customer service.
Apart from this gaffe, the lamp is really super great lighting, solid construction, good light duration. One star deduction for the deficit, they win the goodwill again.
