first, i read the instructions, it states you may have to adjust the transmit frequency of the microphone by adjusting a small screw by the battery cover. i turned on my fm radio to 100.1 MHZ, i kept pressing the vox button and slowly turned the screw (you need a small screwdriver) until i heard the microphone's phrase over the radio, my daughters eyes went wide when dialed in and tried to grab the microphone out of my hand..... She loves it, and wants to sing over my football games... peace robert

My 5 year old recieved this for her birthday and it does not even work. It is the same model as this one but it is pink. The antenea lights up but we have tried it on 2 different with no sound. Save your money for a microphone they can use independently instead of relying on FM waves :(

This toy that I got for Christmas is so not fun! First of all, I thought I would be able to sing in it like a microphone, but no! You have to turn on the radio to some station and when you sing in it it's all fuzzy and bad sounding and if you ever tried to sing in it....people will think you are horrible!
