Works great and genuine streamlight product. Will buy more here if needed

In my opinion, this is one of the better streamlight products. It's certainly sturdier than the original stinger. I use it professionally, and it does occasionally get dropped, with no ill effects. The button does start sticking after a few years. And the lens is NOT scratch resistant, even though it's labeled as such. Heads up . . . when the lens gets sufficiently scratched up, the light out will greatly diminish. Once the lens is replaced, all is back to normal. I'm no glass or plastics expert, but I so far haven't found anything to acceptably polish those plastic lenses. Another thing . . . after several years, the ribbed grip will start to split and separate from the body. On the metal body stingers, if you drop the light, the body will sometimes dent. That doesn't happen with the polystinger. Also, on some of the metal body led stingers, if you drop them, the head will actually start to separate from the body, causing an annoying bad connection. Again, that won't happen with this polystinger.

I use it for checking cows at night and any time I need to have a spot light.

Ordered 4, received 4. They’re great. Oem streamlight battery packs for the survivor and or knucklehead lights. Always a good thing to have a few extra battery packs ready to go in an emergency.

Top brand Did not work. Wouldn't trust another.
