We got these to wear to our local amusement park. They have several holiday events and we love to participate, especially in the evenings. They glow pretty well. I do feel that we have to be very careful putting them on so none of the internal wires break. I am not sure they would break, but I just didn't want to risk it.
They have a slow blink, a fast blink and a steady. There are 6 different light settings.
The batter compartment is at the wrist and is easy to access. The on, off, change pattern switch is on the back of the wrist.
I was hoping they would fit me, but they are definately made for a childs hand. I would buy these again.
