I bought 4 of these. However, two of them showed up damaged, something was rattling on the inside when you moved it. It got replacements for the two, and again had issues with one of them. In total, I have had 7 shipped to me, in order to have 4 working. So the quality control of these should be looked into. DMX in/out are labeled backwards as well.
With all that out of the way, let me say, that if you manage to get some that work, they are a very nice light. The strobe is bright and fast, and the RGBW section looks amazing and gives a nice soft wash light with good colors. I use them in my band, where we have 4 of these behind us on stage, and they run a preprogrammed light show sync to our music. I like the fact that they both function as wash and strobe lights, and it was this feature that sold me on these exact lights.
Final verdict: Check the units carefully for faults when you receive them. If you get some that are working properly, you will get a fantastic light that does both strobe and wash.
