Oh my gosh these are so much fun. We bought these for our nieces 5 and 9 years old, plus one pair for my husband. They are big on the girls and a little tight on him, but the lights are so much fun it doesn't matter! There's different settings for blinking or solid lights or slow color changing. These are awesome to wear late night at family theme parks or out on cold winter walks. You can feel the wires and control box as you wear them, but not enough that its uncomfortable.
