Typically any karaoke event bigger than a small house party is better suited to hiring a mobile karaoke DJ.
Not all karaokes are created equal. The difference in quality between karaoke setups can vary immensely. It is important to do a little research before booking your karaoke DJ to ensure the success of your event. A poor quality or badly run karaoke can do more harm than good so any time spent choosing your supplier wisely is time well spent.
