The Polar RS100 is an introductory heart rate monitor designed for runners who just want he basic heart rate and timing features of a training watch. A lot of the recording and training features found in other higher-end models have been omitted from this product. The Polar RS100 also isn’t compatible with most of the accessories that Polar sells that limit its use to some extent. But if your looking for a no-frills way to help improve your fitness by incorporating heart rate training into you cardio workouts, the RS100 might be right for you.

One of the more important features that’s not included in this product but can be in higher-end models is the Polar Fitness Test. In other monitors, this test measures your personal aerobic fitness level at rest and calculates your personal OwnIndex by evaluating your maximal oxygen uptake or VO2max. The RS100 makes it’s calculations base upon an age-based formula (HRmax = 220 – age), which isn’t as accurate of a reading as the one provided in the Fitness Test.

According to Polar feature list another thing missing from this product is a user replaceable battery. So there’s going to be a cost involved if you ever need to change the battery.
