This disco ball light is so much fun. There is a brace to mount it on the wall or to other things. Or move/remove the brace to set it flat on the top of a speaker or other flat area. There is a remote with many different options. Different colors of red green and blue and diffent combinations of these 3 colors. A flash button does just that, flashes the colors. and tehre are 3 different music buttons. The ball picks up the sounds around it and flash/change/strobe/ with the sounds.It has a regualr wall plug. When it is in rotate mode there are buttons to control the speed from slow to fast. Set this up near any speaker and ahve a colorful night! #rankboosterreview #Sponsored #Peying Source https://www.amazon.com/Projector-Changing-Activated-Rotating-Crystal/dp/B01M28YTFH
