Review on 🎉 USB Mini Disco Light 3-Pack: Sound Activated Party Lights Ball for Halloween DJ Disco Ball Stage - Multi Colors LED Car Atmosphere Light - Magic Strobe Light for Xmas Parties, Pool, Club, Church, Karaoke by Terrance Castle

It does what it says on the tin, a light display that works to the beat of the music. The template shown doesn't change, but for the price it's ok. It still looks cool. The darker the room, the brighter the display on the ceiling and walls. You can't plug it into an outlet, the effect is mainly on the floor. Plug into a surge protector or extension cord placed on a table or shelf for best effect. Can be used outdoors for a party or hangout, but not in the rain. I would buy again and recommend for the price.
