I don't even speak spanish but this mic is excellente.  I read all the reviews and hype and it was as good as advertised- super midrange.  Very warm sound, solidly built.  I had the misfortune of getting a fake sm57 off of ebay and then compared it to this.  The fake was very close, the counterfeiters are getting better and better even had the yellow and green wires and the indentation on the screen on top.  One dead giveaway is the weight, the fake was around 2 0z less and where the mic screws together there is a noticeable gap in a real sm. Not so with the fake it is a very tight closing gap.  I hate to admit it but the fake is not that bad especially for vocals, it doesn't compare with a real one though for instrument recording.  The fake is a more direct counterfeit of a sm 58  imo.  I think it was designed for karaoke from what I've read so it makes sense.
