Summary: Negative side, only 64Mb memory. Positive side, I bought it for a vice recorder and for this it works very well with a couple hours of record time. At $10 how can you go wrong? Also the built in mike has very good quality, I estimate 20hz-16khz range. When compared to my broadcast quality condenser mike, I wouldn't want to have to live on the difference. Software is easy to use on a PC and batteries last 2 forevers.
