I don't know why they advertise and point that feature that doesn't work at all,but for the price and the enhancing the voice in the Karaoke performer I think really worth the cheaper price for what I paid, but it is good the manufacturer must be honest and said what the machine can do and what can't do.

Overall reasonable price

The price is great and so is the product

Overall definitely a great buy at a great price.

Great price

I bought this product due to previous good reviews and its low price

If you need it - do not, but I do not thing that you will find a device at a reasonable price which does it.
