Review on North American Signal PSBLED R Personal Sports & Fitness by Andrew Lyons

I bought this as a gift for my sister who does the morning traffic check at the school she teaches at. Not only is he highly visible and useful for motion control, but he's also popular with the kids at school, who refer to him as their "lightsaber." and as a "reward" for children for completing various personal and class assignments. Even as a pure "safety device" (to be worn when walking, jogging, etc.), this device is definitely worth the money.
