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.
My daughter loves these. I would buy them again.
