    It’s a great light very bright and uses standard 18650 batteries but it won’t sit on end because of the way the button protrudes, beyond that its perfect

    I use the flashlight a couple of times the throw is good and the quality is good but I did find some metal shavings when I unscrewed the endcap cap to put in the battery. Which I found a bit disconcerting but the overall quality is worth $100 even though it is made in China which is fine because you guys don’t charge the exorbitant prices as if it was made in the US like Levi jeans charging the same price as if it was made here but made over there, wherever there is. The brightness is okay though your commercials are a hair bit misleading because you use them in total darkness which in reality eg. the city, the only real effective settings are the 350 lumens and the 1000 lumens. Which are are excellent, I am satisfied very much so with your product.
    Thank you sincerely William L Mitchell.

    Great light. I use it for outdoor, camping, home and…airsoft. That’s why I bought a ‘tactical’ light with strobe function. The only gripe is that the mode memory does not remember the strobe setting… something that’s hard to understand because tactical situations are the only situations in which one does not have time to select the desired mode… an updated model which remembers strobe would be a reason to trade this one in…
