Title: terrible!
Review: This machine is AWFUL! There are two wireless mics which is a great concept but they don't work. One mic has less power than the other so you can't hear two kids at once. Depending on where you locate the machine, neither mic will work without horrible interference or feedback. Stick with a machine that has wires! My daughter tried to use this for about a week and now, the toy is headed for the garbage.
