I am stunned by this level of service and can tell you Streamlight has earned all of my business.

I recently cracked the lens on my Streamlight TLR1-HL during a range of exercises. I don't know when it broke; the light continued to function throughout the exercise. While cleaning the pistol afterward, I noticed the cracked lens. I contacted Streamlight and asked if they could send me a replacement lens and thus avoid sending the entire light in for service. They quickly mailed me a new lens and gasket. On closer inspection, I doubted my ability to mount the new lens as securely as the original lens and as a result, lose the watertight capability. I contacted Streamlight again through a service order, explained my concern, and mailed the entire light back to them. Streamlight acknowledged receipt by email, repaired the light, and returned it with 48 hours. I am stunned by this level of service and can tell you that Streamlight has earned all of my business. Over time, I have purchased 7 of their TLR series weapon lights. All have served me well and the one instance of breakage reported above was repaired in record time without charge. 

Great product. Great warranty. Exceptional service.
