Best light I own!
I own a bunch of effect lights, but the AMDJ Revo4 is bar FAR my favorite one. The programs and animations are incredible. I just set it to random mode (show 1) and sound activated mode. Once I dialed in the sensitivity, it follows the kick drum perfectly. I've also got a wired remote for it so I can easily black it out without DMX control.
Sometimes I point it at the dancefloor, but whenever possible I point it at the wall or ceiling.
I just bought a 2nd Revo 4 so I can slave 2 of them together.
