I bought these panels mainly to integrate with the Sidus app which I use to control my Amaran 100Ds, but these are PHENOMENALLY better than the pair of cheap GVM panels I used to use. I took them along to test at a comedy gig this weekend and they must have been twice as bright as the 8 LED PAR cans the venue had onstage- they really put them to shame. They have really intense colours, and the whites feel as bright as my 100Ds.
Only scope I would like to see for improvement is better ability to control lights live from the app in a gig situation mixing panels and white lights (admittedly not what these are aimed at) and the availability of barn doors to control the light spill from the panels (although the included soft box and grid are admittedly both a great touch, it would be brighter with a barn door)
