I've owned this light since 2014 and have never had a problem with it. It's seen 3 years of hard urban police abuse without ever failing. It's beat on windows, car doors, and more. It's been ran over twice after I dropped it chasing a suspect. I would recommend this light to any cop or anyone who needs a tough light. The best part about the light is the battery life. No it's not quite as bright at some of the stream lights, but the battery life is 10x better. My routine is for every 40 hours of night shift work I charge it. The one stream light I own needs to be charged every shift and a half. If you're looking for a light that won't let you down in -20 degree temps all the way to 100 degree heat this is it.
