Negative: Here, the devil is in the details. There was no sheet thereby; the exact specification therefore remain a mystery. How bright is she now? The Prouktangaben seller are obviously wrong; I have a Olight M20 Warrior similar style with proven 320 lm. So one would have to assume that the specified 1000 lm the Olight would make it look old. No! On the contrary; 320 lm beat the alleged 1000 lm scarce.
These come, that the flashlight is hot during operation, even in low light. What to tell me I do not know; compared to Olight, mine is extremely suspect.
The operation of the modes is very cumbersome. You have to click through the modes with the Hauptschlater. This takes time until the lamp is ready to use (just the bike but it should be straightforward).
In addition, the rubber dissolves in the light chamber.
Conclusion: If you can live with the mentioned points of criticism, has a bright lamp with battery. A high-quality lamp, it is not.
