Bests & Worsts Reviews from Amazon

Well I was very impressed with the look and feel and apparent functionality of the thing. Then I tried to use it. Recorded for a few seconds- appeared to be recording. Then when I hit stop it flashed “file saved” ... THEN the screen turned black except the words “no files found.” It now will do absolutely nothing except say “no files found”. The screen won’t change from that no matter what I do. So apparently it’s dead after the first 20seconds of use.
