So far they have done nothing but take up drive space or add more time to the plugin scan. I got them cheap because they were.....cheap. Stuff I like DrumXchanger, EQ Ranger Plus was a waste even at $4. Maybe that was their game all along is to get some cash on a bunch of plugins that are never going to be updated.
I'm trying to break the get plugins for cheap cycle but that went out the window with Audio Assault.
