Portable SD Phone Call Telephone Voice Recorder Automatic Mp3 Digital Audio Recording with Blue LCD Display

Unit did work, but the audio quality had substantial noise. If you're handy with setting up electronics you should be able to figure out the settings for this machine, but forget about using the instruction book. It's basically gibberish, written by someone who just barely understands the English language. It's over double in price, but the Sangean Dar-101 Audio Recorder records conversations perfectly, is easy to use and has instructions that are understandable.
