I use these with my electronic kit for the feel, not the sound.
The hi hats can be really sharp (I use ear protection because of them) the 16' and 18' are decent, nothing bad or nothing good to say about the sound. I use them both as crashes.
The feeling however over rubber cymbals is night and day. You get the attack and rebound you would get from a normal cymbal, so what you learn translates perfectly to a real kit. Although they are heavier and you feel that.
A positive to that is that you will probably never break these.
I would recommend low volume cymbals for anyone who would get noise complaints and doesn't practice as much because of it. Would I recommend the Zildjan ones? I don't know, I haven't tried the other brands, I think about switching out the HH's sometimes tho.
