Cost and external features (remote sensing cable/USB graphics) were a deciding factor in this purchase. This meter was compared to a calibrated meter in the laboratory and showed the same sound levels. All switching functions work. The software has a nice simple reporting function. The service was very good and local (in Oregon). I had a connection problem and got an answer in the mail the next morning. The software is downloaded from their website and works. I don't expect any problems with it and would recommend it to friends or colleagues.
