I have owned my Streamlight Stylus Pro since 2014. I bought it when I was in school working as a lube tech for GM in my home town. For a year it was constantly dropped in used engine oil, after that it has followed me into the petroleum industry in Canada. My job takes me to all corners of northern Canada and I can say it will operate even in -94°F. No, that is not a miss type! This light has seen gasoline, diesel, and jet fuel: just wipe it off and change the battery a few times and it works like new!
I would recommend any Streamlight products if you want a true workhorse of a product that you can count on!
