That was one of the biggest selling points to me as well. But after my initial, ooohhh I gotta play with this thing all the time reaction, I got bored of it quickly, and in reality forgot it had it most of the time, and you have to be careful, because if you use it and don't have everything set correctly to start with, all music stops playing and you have no volume. The QFX has crossfader effects that you can use to make some interesting mixes, and one of the best features the QFX has over the DJM is the ability to layer effects (meaning using more than one effect simultaneously).
