If possible can tell me how it reacts with the Moyu, Yj, Mefferts, Cyclone boys, SS, Dayan, or Maru cubes?
I have only SS, Dayan, Moyu brands, and the lube is working quite the same on all of them. Maybe a little better on Moyu, and I say that, because my WeiLong responds good to a lot of lube types, but trust me it's nothing special.
If you are curious then just buy Z-Lube and see for yourself how it's working. It isn't too expensive, and even if you wouldn't like it you can use it as a secondary lube or something like that.
