I knew this product when my purchase, very good flashlight, impressive power (unless you want to illuminate a whole field, this lamp for use every day is amply sufficient)
choose between full power (lamp quite heated) and a low power mode, enough to walk on the roads at night, the service life of the battery (2x AA) is not bad, and even more low consumption ..
I did not give it 5 stars because my product is slightly defective, it happens to the lamp turned off while the switch is on, I have shaken up and down it works again. Probably a false contact, but otherwise it works fine.
If you are looking for the best quality / price ratio (best to find it already passes Fenix / Surefire, and it's the same price), I strongly advice you to take this lamp, you will not be disappointed.
