Well pretty much all the money goes into functionality and quality. You can change the brightness from super dim to bright af spotlight, it has strobe mode, beacon mode, police mode and red, blue and green mode. It's also shock resistant, waterproof, and has a long battery life with rechargeable batteries and is small enough to fit in your pocket.
But as well as just wanting a good flashlight, I bought it since I like to walk at night and since I live in a no funz country where you can't even own a taser or pepper spray, so I can use the strobe to blind anyone who tries to accost me. The model is a Nitecore STR7 btw. It's 960 lumens.
