I am a professional home inspector here in Texas. I've been through tons of flashlights by different makers-mostly high-end. This light is top-notch and is critical to my business now. Home inspectors use flashlights for many different tasks. I use this one for "beaming" walls to see imperfections caused by previous flooding, foundation movement, etc. The light is also strong enough to illuminate clear accross all the attics I encounter. I've used it under houses, in the rain, you name it. I once broke the pocket clip off ,(my fault), Surefire sent another one the next day no questions asked. The size of this light is also just right. The clip allows you to just carry it like a pocket knife. If you really need a good light, this is the one to get.
