Review on Calibrated Wavelengths Optical Locator Function by Anthony Mayes

Needed a replacement for my ONX key which I had completely lost (it was only a matter of time!). Ordered and it was great while at work. Startup is pretty quick, simple reading seems pretty accurate. For example, the ability to quickly toggle between auto-off and always-on, which comes in handy when you need to keep the VFL on while running backwards. The VFL is very bright, better than the ones they gave me. It's easy to spot it on the Xbox fiber, even in fairly bright light.
