I bought two sets because I walk in the dark and constantly need to be seen from all sides (front, side and back). I wanted to put two bandages on each arm so I could be seen. I need a bandage all over my arm. Based on the photos, this is pretty much what the bracelets will cover up. It's not relevant. Photos are misleading. For small arms, the bandage covers a maximum of half of the arm. You have to choose which part you want to illuminate: front, side, back. They are also very small. In a thin jacket they would be very tight. I've attached a photo below. The quality seems very good and the light seems very good, they just don't cover much. I thought we would just join the two together to make one long band for each arm, but you can't see the bands. See photo below.
