I'm a property manager in a low-income part of town. My wife gave me grief when I purchased my SureFire E1B Backup®because she thinks flashlights should only cost five dollars. I mainly wanted the light, which has a high and low setting, to use the low setting to see my receipt book, because tenants have a bad habit of leaving their porch lights off when I come to collect the rent. But I quickly realized that the Backup's two settings allowed me to not only see my receipts, but also in the bushes and all around the house. I was out collecting rent, when a man approached me and said that I owed him money for work he'd done for me, but I'd never even met him before. I took my Backup and shined it in the opposite direction, where I discovered his friend sneaking up on me from the other side of the house. I then turned and shined the light directly in the first guy's eyes. He actually let out a yelp, declaring that he'd been blinded. This bought me a few precious seconds to get back in my truck and the hell out of there. Thanks, SureFire.
