Good, Easy to use, small package.
Just plug and play, no doubt it's a bit expensive but the mic is worth every penny. The audio digital converter as many Apogee products is fantastic. I do suggest to download the Tascam PcmRecMKII app or Apogee MetaRecorder.
My only complain is that the USB cable is only 0.5m I wich it comes with a 3 or 5 meter cable.
