I am not really a drummer anymore, nor was I ever much of one. I do remember what electronic drums were like--they were awful. Cheap, sluggish, and they sounded terrible. I thought that the market for these things was reduced to triggering effects and not much else.
And while this probably seems like some sort of cheesy ad, it's not. I can't believe how good these things sound. They sound very responsive and like they are of pretty high quality.

Again, this is not an ad of any kind. It's more of a 'holy crap--when did they find time to make these things actually sound good' thing.
