Regular user of batteries for my job recorder, it is with satisfaction that I switched to this recorder. On Windows 8 no software to download, immediately recognizable key, long recording (I have recorded a meeting of 8 hours and it did not seem out of breath-contrary to me -) and then clear and convenient playback. Getting started: on / off, loading space via USB on your PC: nothing simpler. I am fully satisfied with this product that relegates my recorder batteries now in a drawer.
