Garbage! This product does not remotely work as advertised. The sound stinks. There is no customer support from the company! If you buy this hunk of junk you will have to pay Overstock.com the shipping cost to take it back, and you will send this steaming pile of crap back! Do yourself a favor and do not buy this junk!
I purchased this karaoke machine on another site a month ago and I am very pleased with it. It is very loud, has great Echo and reverb and the Bluetooth feature works perfectly. The only issue I have is with the built in radio, but I rarely listen to radio anymore anyway. I use Spotify and Pandora on the Internet. So far I am happy with this system. The microphone works great and the volume is adjustable.
