I purchased this voice recorder to use to record school lectures and spend a considerable amount of time researching which recorder that I wanted. This recorder is compact, sleek, is MP3 compatible and has ample memory for my needs. However, I was unable to download my recordings onto my computer either through the Diasonic software or XP's device manager. Eventually the whole unit stopped working. Also, I had to take the batteries out even when it was off or they would be drained when I went to use them. The recording and microphone quality was excellent, but I could not queue forward or backward during playback. When I tried to contact customer service, I found that it is made from a company in Korea and I was unable to contact anyone to help me. It does come with a 1 year warranty, but it sure would be nice if you didn't have to use it. I definitely would never buy from this company again. I'm going with an Olympus.
