Summary: This isn't a review of the recorder as such, but of the price, which is completely absurd. For around $50 more, you could buy a brand-new professional-grade dictation recorder like the Olympus DS-7000 or Philips DPM-8000.
Summary: Sony M570V did not work at all. I put fresh batteries in it, tried testing it but rollers would not rol the tape in the recorder. I am requesting a full refund in the original manner in which I paid.
