Review on Ezer Light Up LED Armbands for Running - Stay Visible and Safe with 2 Pack Reflective Gear Flashing LED Sports Wristbands by Joseph Hall

I wanted to like it, but I can't. The first problem is that they don't fit snugly on the hands. No matter how much I tighten the straps, after a few minutes they loosen and it falls off my arm. The second issue I encountered was the brightness, or lack thereof. These are not bright at all. To be honest, the $6 lighted collar I bought for our dog is a lot brighter. All in all, I'd say look for a different brand backlit headband if you want to be seen while you run.
