I hired them for a wedding reception. They're very good, and you can hire them, do nothing and they'll do a great job. In my case, I was a little more hands-on and had compiled a song list from their library. I was disappointed that they didn't stick to the list. Other than that, I thought they were overly loud, and asked for a volume reduction that didn't occur. They have their routine, and they do it very well. If you're inclined to let them run with it, you can be confident that they'll do a fine job.
