I have an XR15 G5 Pro. The light fixture itself is fine, however, you need to use the Mobius software to actually use it....and the Mobius software is horrible. I spent three or four hours on TWO separate occasions trying to connect to my light, not to mention additional time reprogramming all the settings because my settings were wiped out.
Maybe the Mobius problems are resolved, maybe they aren't.......time will tell. I have already stated in another thread that I will take a hammer to it the next time I can't connect to it and replace it with something else from another manufacturer.
