I use a Streamlight TLR-2, which is a flashlight and laser, but the TLR-1 is a light only. Mine is at least five years old, maybe a year or two older, and it's held up well. The warranty is phenomenal. I had a problem with the laser fading in and out and sent it in after getting a service authorization number. It was back in a week with a new laser module and it didn't cost a dime (except to ship it to them). It's got a lifetime warranty that the company stood behind without even asking if I was the original owner or if I dropped it or whatever. 'Course, they're expensive, but the base product is high quality and the warranty can't be beat, so you're getting what you pay for. It's the only one I've used so I can't compare it to anything else. Hope that helps.
