This is my first DMX light, so I don't really know what to expect. From my perspective, however, this is great. The colors seem vivid enough to me, and it's plenty bright (I can't look directly into it when it's on its brightest setting).
I'm using it in DMX mode, where I control each individual pixel through a Python script, and I've had zero problems in doing this (I'm feeding it via the Eurolite USB-DMX512-Interface/Update-Ad).
If you want certain modes or effects, you should read the manual beforehand to make sure it's in there, but if you're a beginner like me and want to control it in about the same way, I'm pretty sure you'll be happy with it.
