Review on Enhanced Performance: MIC520 Wireless Microphone System- Dual Handheld UHF, Rechargeable Receiver for Karaoke, Singing, PA Systems, Parties- 260ft Range by Laura Evans

I bought this for a fun little karaoke stage in our apartment. It was great fun. I didn't have to do much customization for this product. You just turn it on and you can start talking. You just have to turn on the transmitter and receiver and they will be paired automatically. If you're buying this for professional use it might not be as loud as you'd like in a very large room, but it works great for parties and small events.
