I've had about 6 months and it remains edc in my backpack. Super lighting has full power and low fashion very useful and do not dazzled when seeking something in his bag. Resistant and échanche: it's not hype I threw it on the ground and in the creek and it has not a scratch nor a drop of water has interrieur. I did not give it 5 stars because its one small defect is that the low mode is sometimes dificult to have because you have to screw the lamp head to illuminate it and the low mode is a small pin fitted in spring that barely exceeds the principal so hard pellet chopper. I think I'm going to help add some weld tin on the pin to lengthen a bit and have more ease to have the low mode. One good happens found the low fashion but sometimes touchy! I recommend this very small and really not expensive for the quality and lamp power
