I bought these gloves about two years ago and never went to a concert to use them. All the batteries in the gloves should be fresh and ready to go. These gloves have a variety of colors and modes. You can swap through the colors and set them to each individual finger. You can also select the mode that the lights blink in. I believe there are 5 modes and 20-25 different colors. These are the Emazing lights Flow v2 gloves. All lights work. All lights have batteries. Text 720-309-7005 if interested!
