Very good product is the. SONY. I use it to make his pro made comments to include in presentation videos. Combined with a lavalier Boya at 17i the result is surprising quality. By cons it comes with a clip-on microphone that SONY is not reported in the description which forced me to buy one. It is very simple and intuitive to use, despite many features. Huge battery autonomy both in storage. It lacks backlighting but good considering the price. As against the accompanying software is very basic; but few connect the voice recorder usb to a computer and easily recover files mp3 sounds and the work with his favorite software. In short very good very versatile product with a quality and low price. Amazon perfect delivery.
