Once it is working, it does a good job. I had trouble linking the watch to the monitor; the trouble shooting instructions are limited, so I had to call Suunto, who were very helpful. I reveresed the monitor battery for 10 seconds and that fixed whatever the problem was. The monitor links itself automatically to all the kit at the gym, so I only need the watch when I am outside. The display is clear, though the stopwatch doesn't have great functionality. The rest is pretty easy to set up and use. It does what I need it to do without any fuss.
