Several persons hate this kinds of tremolos because they played with cheap licensed floyd rose tremolos, those tremolos that comes in "cheap guitars" are just crap, why? They are done with easy bend and deformable material, making the intonation change every time you play a string. The schaller is hard as hell, if you like to make dive bombs and get crazy with the tremolo bar install one of this. Definitely a must update for your axe. Never go out of intonation, even if you are a viking playing guitar during the vahalla of your father.
