Bought a pair. Solid building, great colours combination, including separated control over the colour LED that surrounds the octagonal shape, and the three amber/white bars in the. middle . Very strong intensity light, and goes amazingly well with the new pole stands (mine are the K&M), you may need adapters. The units can work stand alone, but you will have the better control with a DMX controller for total setting options, preferably not a basic one as you will have to compromise some channels. I have the Eurolite Easy Operator Deluxe, is not the ideal because the limitation in channels and I need to operate on 10 channels mode. For me it is enough, as I like more static light settings than "party time lights". Final thought, bear in mind these units are big, and depending on the size of stages/venues you play, you may consider the smaller versions.
