Review from
Cycling Weekly
Hot on the heels of the release of the all-singing, all-dancing CS600 comes the CS400. Only lacking a few hardcore features, mainly the ability to expand with the Polar power unit...Most importantly the CS400 comes with the same updated Polar Pro-trainer 5 software. This is a major improvement on previous Polar software and enables users to review both training and performance as well as program specific training sessions. It can also be used to transfer settings and values into the head unit which is far easier than doing it manually.
In conclusion...
The CS400 has everything that all but the most fanatical and dedicated trainer would desire in a cycling computer.
