CS300 Polar Heart Rate Monitor
Charlie Bell, July 5, 2011
Convinced by Polar’s reputation as a leading manufacturer of sports instruments, I invested in a CS300 during the 2006 season to track my cycling training. Five years later, I now swear by the product, taking it out on rides on the mountain and on the road. It took three years and hundreds of hours of usage before my CS300 battery ran out, and Polar just three days to find and mail fresh replacement. As a example of how simple tech can enhance and simplify the training process, my experiences with the CS300 are almost entirely positive.
