parkfein wrote a review of Polar S120 Heart Rate Monitor Watch on December 6, 2004
My first monitor just tracked my heartrate, but didn't track my workout time and didn't show the time of day. I'm very happy with the S120 - it does all that and more. One nice feature is that you can set it to beep at you when your heart rate falls below your pre-set level -- so you know when you need to kick it back up a notch. It also has many more features that I don't use, but might some day. I definitely recommend this product.
