Review on Verkstar Karaoke Bluetooth Microphone: Portable Wireless Handheld Mic with Colorful LED Lights - Perfect Christmas & Birthday Gift for Kids and Adults by Collin Jackson

It was pretty easy to use for those who understand Bluetooth and how to connect it, other than that the instructions weren't great. But in principle you can sing to the music. It doesn't really have other functions, or those that it has are meaningless. It brought us joy on Christmas Day when we sang Christmas carols.
