I am using a D1 1000ws monoblock which comes out of the box. This is a very useful toy. Works the same as the $500 Profoto remote. Only thing annoying is that you have no idea what power the flash is set to. So it works just like the Profoto version with the same problem. They didn't improve the Profoto version, they just copied it! So for $80 it's great! You don't have to constantly go to the flash and change the power.
