The product does exactly what it claims to, but leaves something to be desired. Your singing volume and the volume of your music can't be adjusted independently, so you end up with the music always being too quiet and your voice always being to loud. I originally bought this for my girl friend so that she could sing along with her music on long car trips, but since you are completely surrounded by speakers in the car, the feedback is deafening. Even using it at home wasn't practical, because in her small apartment we couldn't get far enough away from the speakers. If we turned it up loud enough to hear the music, the vocals were blaring and caused feedback. If we toned the volume down enough to reduce feedback then you couldn't hear the music at all.Not worth the money. I was disappointed.
