The app for this device is poorly designed. The light is both too intense and too narrow, like looking at the beam of a flashlight (even with a diffuser). Worst of all, the battery doesn't last the entire class or meeting. It was meant for photography, so if you're ordering it for that, great. Your phone has a great camera, use it. Don't use it.
